Heavy metal oxide glasses in the system TeO2-PbO-WO3 doped by selected rare earth ions have been presented. The method of their preparation and physical properties were determined. Infrared luminescence of Er3+ and Tm3+ ions embedded in TeO2-PbO-WO3 glass hosts is reported for room and helium liquid temperatures. The substantial influence of energy transfer processes between the glass host and Er3+ and Tm3+ doped ions is shown experimentally through the dependences of photoluminescence on light polarization and excitation wavelength. The presented spectra of the rare earth doped glasses indicate on a possibility of their excitation by the Nd-YAG laser with wavelength about 1,06 um. Because of their properties this kind of glasses can be used for construction of optoelectronic devices.
