Abstract:

Sample of glass systems with compositions (X% BaO – (100-x)% P2O5 ), (X% CaO – (100-x)% P2O5 ), (X% MgO – (100-x)% P2O5) where (x=20,30,40,50) were prepared .The result of investigations of density, optical absorption, refractive index, and infrared spectra are reported. The density measurements show that the density increases with BaO, CaO, and MgO content in the glass systems. The optical absorption measurements show that the fundamental absorption edge in the optical absorption is due
to the forbidden indirect transition. The optical band gaps (Eopt) show a decreasing trend with an increasing amount of BaO, CaO, and MgO in the glass network. The glass exhibit a high refractive index and are useful for solid-state laser and optoelectronic devices. From the infrared absorption spectra, it is found that the addition of BaO, CaO, and MgO does not introduce any new absorption band in the infrared spectrum of the glass system.
