Deep Uv Raman 深紫外拉曼
In this study, we test the feasibility of a deep UV Raman spectrometer for the detection of nitrate/nitrite, selected pharmaceuticals and the most widespread microplastic polymers. [1] We developed a state-of-the-art, high-efficiency standoff deep UV Raman spectrometer. [2] In 2020, NASA Mars 2020 mission will send a rover equiped with a combined LIBS/Raman instrument for remote analysis (SuperCam) as well as proximity science instruments at fine scale for X-ray fluorescence called PIXL for Planetary Instrument for X-ray Lithochemistry, and deep UV Raman spectroscopy called SHERLOC for Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals. [3] In this report, we will present our recent efforts on improving reliability and simplicity of deep UV Raman spectroscopy, which provides much improved sensitivity and specificity of detection (for example, we can routinely distinguish Coke® from Diet Coke® in a matter of milliseconds). [4] SHERLOC, a deep UV Raman/Fluorescence spectrometer has the ability to detect and map the distribution of many organic compounds, including the aromatic molecules that are fundamental building blocks of life on Earth, at concentrations down to 1 ppm. [5] Deep UV Raman spectroscopy is an exquisite tool for chemical sensing and imaging, which provides superior sensitivity and specificity, while allowing Raman measurements to be performed in a bright room with no residual fluorescence background, which can potentially corrupt the useful signal. [6]在这项研究中，我们测试了深紫外拉曼光谱仪检测硝酸盐/亚硝酸盐、选定药物和最普遍的微塑料聚合物的可行性。 [1] 我们开发了一种最先进的高效对峙深紫外拉曼光谱仪。 [2] 2020 年，美国宇航局火星 2020 任务将派出配备用于远程分析的组合 LIBS/拉曼仪器 (SuperCam) 以及用于 X 射线荧光的精细尺度接近科学仪器（称为用于 X 射线岩石化学行星仪器的 PIXL）的漫游车，和称为 SHERLOC 的深紫外拉曼光谱，用于使用拉曼和发光对有机物和化学品进行扫描可居住环境。 [3] 在本报告中，我们将介绍我们最近在提高深紫外拉曼光谱的可靠性和简单性方面所做的努力，这大大提高了检测的灵敏度和特异性（例如，我们通常可以在几毫秒内区分可乐®和健怡可乐®） . [4] SHERLOC 是一款深紫外拉曼/荧光光谱仪，能够检测和绘制许多有机化合物的分布图，包括浓度低至 1 ppm 的作为地球生命基本组成部分的芳香分子。 [5] 深紫外拉曼光谱是一种用于化学传感和成像的精致工具，它提供了卓越的灵敏度和特异性，同时允许在明亮的房间中进行拉曼测量，没有残留的荧光背景，这可能会破坏有用的信号。 [6]
uv raman spectroscopy 紫外拉曼光谱
Physicochemical properties of the obtained MTT zeolites were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, N2 physisorption, NH3-TPD, 27Al NMR, 13C NMR, 11B NMR, UV–visible spectroscopy, and UV Raman spectroscopy. [1] Results are reproduced with surface-sensitive near-UV Raman spectroscopy on BF 2 + ion implanted and laser thermal annealed (LTA) Si, demonstrating the full portability of the Raman technique to state-of-the-art nanoelectronics. [2] We combine genome mining, metabolic profiling, MALDI‐Imaging and UV Raman spectroscopy, to detect, identify and visualize a complex of chemical mediators and toxins produced by the pathogen during the infection process, including toxoflavin, caryoynencin, and sinapigladioside. [3] Herein, based on the elaborate experimental design/implementation and structural characterizations including UV Raman spectroscopy excited at 244 nm, 11B MAS NMR, 29Si MAS NMR and FT-IR spectroscopy, etc. [4] The vanadium existence was characterized by IR spectroscopy, UV–vis diffuse reflectance spectra, UV Raman spectroscopy, and 51V, 29Si and 31P NMR spectra. [5] The use of operando UV Raman spectroscopy reveals distinct changes in the surface vanadia structure including breakage of V O V bonds and a partial reduction of vanadyl, as well as the formation of support hydroxyl groups, while the presence of CO2 is observed to prevent coke deposition. [6] A detailed analysis of various parameters such as: Dispersion (G), I(D)/I(G), T-peak position and FWHM(G) obtained from UV Raman spectroscopy for flat and particulate region of all DLC specimens indicate that the vibrational properties vary in both the regions depending on growth mechanism and modification of particulates in the plasma, respectively. [7] In 2020, NASA Mars 2020 mission will send a rover equiped with a combined LIBS/Raman instrument for remote analysis (SuperCam) as well as proximity science instruments at fine scale for X-ray fluorescence called PIXL for Planetary Instrument for X-ray Lithochemistry, and deep UV Raman spectroscopy called SHERLOC for Scanning Habitable Environments with Raman & Luminescence for Organics & Chemicals. [8] In this report, we will present our recent efforts on improving reliability and simplicity of deep UV Raman spectroscopy, which provides much improved sensitivity and specificity of detection (for example, we can routinely distinguish Coke® from Diet Coke® in a matter of milliseconds). [9] In this paper, SYSU-6 is characterized by single-crystal/powder X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray analysis, transmission electron microscopy, infrared and UV Raman spectroscopy, solid-state 27Al, 31P and 13C magic angle spinning (MAS) NMR spectra, and elemental analysis. [10] One of the hurdles to be overcome to allow deep-UV Raman spectroscopy to become accessible is a direct method of calibrating both the observation frequency and detector response of the spectrograph being used. [11] Finally, we demonstrate the applicability of the system for DUV Raman spectroscopy by collecting a high dynamic range, high spectral resolution spontaneous Raman spectrum of air. [12] Thermal conductivity characteristics of Si nanowires (SiNWs) treated with thermal oxidation before and after a subsequent Ar+ ion irradiation process were evaluated by UV Raman spectroscopy, in order to investigate the impact of interfacial oxide-induced lattice disorder. [13] 5 nm with 160 μW output power suitable for UV Raman spectroscopy. [14] Deep-UV Raman spectroscopy is a promising method for the analysis of nitrates and nitrites in water at ppm (mg/l) concentrations. [15] The successful formation of a VOx–support interphase is confirmed by UV Raman spectroscopy. [16] As a powerful and sensitive tool for the characterization of zeolite building units, UV Raman spectroscopy has been used to monitor interzeolite transformation from FAU to CHA and MFI zeolites. [17] Deep UV Raman spectroscopy is an exquisite tool for chemical sensing and imaging, which provides superior sensitivity and specificity, while allowing Raman measurements to be performed in a bright room with no residual fluorescence background, which can potentially corrupt the useful signal.

UV Raman spectra were measured using a novel experimental configuration. [1] Raman measurement of Tryptophan on an aluminum nanopore structure with excitation from our tunable OPO system in the visible and deep UV region indicate visible excitation causes more fluorescence and is less specific for the tryptophan, even displaying a Raman peak at the silicon substrate, while the deep-UV Raman spectra, at an energy close to the nanopore resonance, shows no substrate signal and peaks with close correlation to the known tryptophan vibrations. [2]使用新的实验配置测量紫外拉曼光谱。 [1] 在可见光和深紫外区域使用我们的可调谐 OPO 系统激发的铝纳米孔结构上色氨酸的拉曼测量表明，可见光激发会产生更多荧光，并且对色氨酸的特异性较低，甚至在硅基板上显示拉曼峰，而深-UV拉曼光谱，在接近纳米孔共振的能量下，没有显示底物信号和与已知色氨酸振动密切相关的峰。 [2]
