Tm3+-Ho3+共掺杂的碲酸盐玻璃2μm荧光性质
摘要
The emission properties of 2-m region fluorescence of Tm 3+ -Ho 3+ co-doped tellurite glasses are investigated. Introducing F -ions to the composition of tellurite glasses plays a positive effect on the 2-m emission. A maximum intensity of 2-m emission is achieved when 1.5-mol% Tm2O3 and 1-mol% Ho2O3 concentration are doped in the glasses. The emission cross section and gain coefficient of the 5 I 8 5 I 7 transition of Ho 3+ are calculated. The emission cross section has a maximum of 1.2910 -20 cm 2 at 2048 nm wavelength. The results indicate that Tm 3+ -Ho 3+ co-doped tellurite glasses are suitable for 2-m application.
