dc.description.abstractDiffuse reflectance spectroscopy (DRS) measurement has been carried out on pure and electron irradiated single crystal samples of SrTiO3. Interestingly, it has been observed that electron-irradiated sample have new absorption peak in optical absorption spectra. In order to understand the origin of a new absorption peak in electron irradiated sample, first principle calculation for optical spectra considering defects at Sr, Ti and O site using GGA + approximation have been carried out. It has been observed that the features present in the experimental optical absorption spectra match with that of simulated one having oxygen vacancy. Present investigation suggests that high energy electron irradiation produces oxygen defects in SrTiO3 and DRS is found to be a useful technique to probe the signature of such defects experimentally. © 2018 IOP Publishing Ltd.en_US
