Abstract
Synthesis of glass system with the composition (mol. %) 50P 2O5-(50 - x)Li2O - xZnO + 5 wt % Dy 2O3 has been described. IR absorption spectra and the kinetics of cathodeluminescence at x ranges from 0 up to 50 has been investigated. With the replacement of Li by Zn, a decrease of the oxygen ions' packing density and the average phosphate chain length could be observed. The increase of the ZnO quantity in the glass composition results in the luminescence decay time decreased from 240 to 50 μs in the 481 and 573 nm bands: here, the branching coefficient for the 4F9/2 energy level undergoes changes. The luminescence kinetics are well described by the Inokyti-Hiroyama model for the dipole-dipole mechanism.
