摘要：

We have investigated the thermal and spectroscopic properties of Pr3+-doped new tellurite matrix with the molar composition 60%TeO2-27%WO3-10%PbO-3%Lu2O3 (TWPLu). The differential thermal analysis has shown that addition of Lu2O3 to the glass results in an increasing resistance against crystallization. The ellipsometric data have provided a Sellmeier-type dispersion relations of the refractive index of the investigated glasses. The optical absorption edge of the TWPLu matrix has been described within the Urbach approach, while the absorption and fluorescence spectra of the Pr3+-doped TWPLu glasses have been analyzed in terms of the standard Judd-Ofelt theory along with the luminescence decay of the P-3(0) and D-1(2) levels of the Pr3+ ion. A significant influence of the Pr3+ ion concentration on the photoluminescence intensity as well as on decrease of the lifetimes of both levels has been explained by a non-radiative energy transfer between the ions through cross-relaxation and energy migration processes.
