Optical Absorbance Studies of Transition Metal Oxides Containing Lithium Borosilicate Glasses

The glass samples represented by general formula 30LiO₂: (70-X) (6/7B₂O₃:1/7SiO₂): XTMO (X=0, 0.05, 0.1) were synthesized by conventional quenching technique. The TMOs i.e., Cr₂O₃, MnO₂, Fe₂O₃ and Co₃O₄ were added at the cost of both formers. The study of optical absorbance of the glasses has been carried out. The UV-Visible absorbance of spectra has been studied by using the Fiber optic spectrometer. The observed absorbance bands are typical of the transition metal added to the glass. The optical absorbance results indicate that the glasses containing chromium, manganese and cobalt have a good potential to be developed as optical filters for specific wavelengths in the visible range.
