Spectroscopic Studies of Chromium Doped Boric Acid Glass (BAG)

Abstract

Chromium-doped boric acid glasses (BAG) were synthesized by rapid quenching techniquein appropriate proportions of a mixture of H₃BO₃, Pb₂O₃, and ZnO in the temperature range of 1050⁰C-1150⁰C. Cr₂O₃ has been used to dope chromium ions as Cr³⁺. Optical spectra were recorded by UV-VIS and Raman spectroscopy. The glassy nature of the samples has been confirmed by X-ray diffraction (XRD). Laser Raman spectra have been recorded using 532nm and 750nm to study the vibrational nature of the glass structure. Chromium-doped boric acid glasses show BO₃ and BO₄ structural units in the FT-IR studies.Chromium-dopedboricacidglassesshowBO₃andBO₄structuralunitsintheFT-IRstudies.
