Systematic series of lead-bismuth phosphate glasses, where PbO, Bi2O3 and P2O5 content change for every series based on their weight percentage have been prepared. The optical properties were measured and their amorphous nature was confirmed by X-ray diffraction technique. Both experiments were conducted at room temperature. The fundamental absorption edge for all the glasses was analyzed. The values of refractive index, also the position of absorption edge and hence the optical band gap were found to vary depending on the composition of the glass.
