摘要：
In this work, Tm3+ doped and Tm3+/Ho3+ co-doped germanate glasses with various TiO2 concentrations have been examined using optical spectroscopy. The broad emission bands corresponding to 3F4 -> 3H6 (1.8 mu m) and 5I7 -> 5I8 (2 mu m) transitions of thulium and holmium ions were registered, respectively. It was observed that the intensity of near-infrared emission bands significantly changes with increasing titanium oxide content in the glass composition. Furthermore, the energy transfer process from Tm3+ to Ho3+ ions in studied glass systems was confirmed and discussed. The dependence of spectroscopic parameters like full width at half maximum (FWHM) and energy transfer efficiency (eta ET) on increased TiO2 concentration in glass host was established.
