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 ...
The ability to shape the index profile of optical fibers holds the key to fully flexible engineering of their optical properties and future applications. We present a new approach for the development of a graded index fused silica fiber based on core nan
(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 ...
Raman spectrum confirmed the deposition of pure anatase phase TiO2 on fused silica. Luminescence of self-trapped excitons and oxygen vacancies were observed in anatase NCs. The indirect band gap of A–TiO2 was determined to be 3.14 ± 0.01 eV by analyzing the surface photovoltage spectrum. Energy...
Moreover, the fabrication defect attributed to the heat accumulation effect is analyzed by Raman spectrum. A scanning strategy is put forward to compensate the asymmetry in the cross section of the micro channels.doi:10.1016/j.jmapro.2020.03.057Han Wang...
