Abstract

Tb3+ doped borogermanate glasses with 30B2O3-40GeO2-(30-x)Gd2O3-xTb2O3 (x=1,2,3,5 and 7mol%) composition have been prepared by conventional melt quenching technique. The optical and luminescenceproperties of prepared glasses were characterized by absorption, photoluminescence and decay time measurements.The photoluminescence spectra of Tb3+ doped borogermanate glasses exhibit intense emission in green region(5D4→7FJ , J = 3,4,5 and 6) and weak emission in blue region (5D3→7FJ , J = 3,4 and 5) under 378 nm excitation.Among them 5D4→7F5 transition (541 nm) gives the most intense green emission. Concentration quenching isobserved beyond the doping level of x=5. The ratios of integrated emission intensities of 5D4→7F5 to 4D3→7F4transitions called as green to blue ratio (G/B) have been evaluated as a function of Tb3+ ion concentration. Decaytime of 5D4→7F5 transition of Tb3+ ions was found to be 1.801 ms. The color coordinates of the prepared glasses arelocated at the green region of the CIE diagram.
