Paper Abstract

In this paper the analysis of upconversion luminescence dynamics in tellurite and germanate glasses doped with Ho3+ and sensitized by Yb3+ in 8:1 molar ratio was presented. Population of energy levels was calculated using Runge-Kutta method. The influence of pump power (976 nm) radiation on population of excited levels and the possible upconversion mechanisms were analyzed. The energy transfer coefficient in tellurite glass CD2 = 5,0 x 10-18 cm3/s, CD3 = 1,5 x 10-17 cm3/s and CD4 = 9,0 x 10-17 cm3/s and in germanate glass CD2 = 2,80 x 10-18 cm3/s, CD3 = 6,35 x 10-18 cm cm3/s and CD4 = 3,56 x 10-17 cm3/s were used to analyze dynamics of upconversion processes.
