Abstract
Abstract We report, fused silica samples have been processed with various grit sizes (3, 5, 12 and 25 μm) of Aluminium oxide (Al2O3) abrasives. Aluminium oxide has a significant effect on the vibrational and optical properties of the silica glass. The prepared samples were characterized through UV–Vis spectroscopy, Photoluminescence spectroscopy and Raman spectroscopic technique to understand the effect of aluminium oxide powders with different grit size on the silica glass. The transmittance spectra of all the fused silica samples excellent transmission at far infrared and visible region up to approximately 2750 nm. The steady-state photoluminescence (PL) measurement of all the samples was performed under excitation wavelength of 300 nm at room temperature which shows the maximum emission peak at 430 nm. The typical Raman spectra for all the samples were recorded at 532 nm excitation at room temperature to study the Alumina abrasive induced vibrational properties.
