Abstract

(PbO) 30(ZnO) 20(P 2O 5) 50-x(Nd 2O 3) x and (PbO) 30(ZnO) 20(P 2O 5) 50-x(Sm 2O 3) x glasses (where x=0.5, 1, 2%) have been prepared by conventional melt quenching method. Measurements of X-ray diffractrogram reveal samples prepared are amorphous in nature, DSC studies have been made and the glass transition temperature (T g), crystallization temperature (T c) and glass stability factor have been evaluated. These glasses exhibit high transition temperature (T g) and high stability factor (S) indicating glasses are stable. IR spectra of these glasses show absorption peaks at 1215cm -1, 1072cm -1 and 728cm -1 corresponding to P=O, P-O-P and P-O - vibrations. Optical absorption studies show absorption peaks in the range of 462.5-584 nm for various transition in the Nd 3+ ion and 287.5-562.5 nm in case Sm 3+. © 2011 American Institute of Physics.
