Raman microscopy is identified for understanding the improvement in chemical structure integrity of the fused silica. Power spectrum density characteristics of fused silica shows 80% reduction in higher spatial wave length after plasma processing which signifies improvement in surface figure. Life of the ...
This paper discusses the two sharp lines which are seen at 495 cm -1 and 606 cm -1 in the Raman spectrum of pure fused silica. We conclude that the 495 cm -1 line is probably a longitudinal optical mode of the network, although defect... FL Galeener,JCM Jr,NM Johnson - 《Physics...
Laser Raman spectrum of optical fiber and the measurement of temperature field in space The temperature effect of laser Raman scattering spectrum of optical fiber was researched. We applied the optical time domain reflection technique of optic... Z Zhang,T Liu,X Chen,... - 《Proceedings of ...
(1.57 mmol) were loaded into a 15 mL zirconia jar with a 10 mm∅zirconia ball (3.08 g) and milled at 30 Hz for 10 min. The crude mixture was suspended in DCM and dry loaded onto silica gel. Column chromatography was performed (eluent: from 100% hexane to hexane:...
The low frequency Raman spectrum has been investigated for porous silica aerogels progressively densified, starting from a mass-fractal sample to obtain finally fused silica. The spectra show a broad peak due to modes characteristic of the constituent particles of mean dimension a. In the first ...
Large area photomask substrates of fused silica (type III) and a size of up to 9" x 9" are locally evaluated by laser induced fluorescence (LIF) and H_2 measurements. Using a narrow-bandwidth KrF excimer laser, pulsed UV Raman spectroscopy is applied to measure the content of molecular ...
