Abstract
Fourier transform infra red (FTIR) and energy band gap of potassium lithium borate glasses of different composition have been studied using Fourier FTIR and UV-VIS spectroscopy techniques. The glasses were melted in the alumina crucible in an electric furnace at 1100°C for 30 min until homogenous melt was obtained. The X-ray diffraction analysis was adopted for confirming the amorphous nature of glass samples. From optical data direct, indirect energy band gap and cutoff wavelength has been calculated.
Key words: Energy band gap, Fourier transform infra red (FTIR), X-ray diffraction, UV-VIS spectroscopy, amorphous.
