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 C_^D2 = 5,0 x 10^-18 cm^³/s, C_D3 = 1,5 x 10^-17 cm³/s and C_{_D4} = 9,0 x 10^{^-17} cm³/s and in germanate glass C_D2 = 2,80 x 10^-18 cm³/s, C_D3 = 6,35 x 10^-18 cm cm³/s and C_D4 = 3,56 x 10^-17 cm³/s were used to analyze dynamics of upconversion processes.
