Structural and Luminescence Study of Rare Earth and Transition Metal Ions Doped Lead Zinc Borophosphate Glasses

Abstract

A series of glasses with composition of x PbO-(50- x )ZnO- y B 2 O 3 -(50- y )P 2 O 5 with 0 x 50 mol% and 10 y 20 mol% were prepared by melt quenching technique, with 30 minutes pre-heating and 10 minutes for melting. The structural properties of prepared samples were studied using Fourier Transform-Infrared spectroscopy. The glasses were mainly based on PO 2 , BOP and BO 3 unit. In order to obtain luminescence properties, another series of sample at composition 20PbO-30ZnO-10B 2 O 3 -40P 2 O 5 doped with Fe 2+ , Ti 2+ , Y 2+ and Nd 2+ were prepared. These samples were investigated using Photoluminescence Spectroscopy with different excitation wavelength to compare results. Results showed that with the presence of rare earth and transition metal ions as activator in lead zinc borophosphate glass system give rise to luminescence of visible light.
