Description
Summary:A series of aluminum, lead phosphate glasses with chemical composition 70P 2 O 5 –5Al 2 O 3 –(25-x) Na 2 O-x PbO, where x = (0, 5, 10, 15, 20 and 25 mol%) have been prepared and synthesized using a conventional melting method. The structural analysis has been performed using FTIR techniques. FT-IR confirmed that PbO 4 , and AlO 4 are structural units. The optical absorption spectra have been studied and the optical band gap has been estimated. The optical band gap increases with increasing the concentration of PbO. The physical parameters such as density, electronegativity (χ), electron polarizability (α°), optical basicity (˄), molar refractivity R m , molar polarizability α m , urbach energy (E u ) and elastic moduli are increased.
