Abstract

The invention discloses Er<3+> / Ce<3+> / Yb<3+> tri-doped tellurate glass containing silver nano particles and a preparation method thereof. The glass consists of the following components in percentage by mole: 65-75mol% of TeO2, 5-10mol% of Bi2O3, 10-20mol% of ZnO, 5-10mol% of Na2O, 0.1-1.0mol% of Er2O3, 0.1-1.0mol% of Ce2O3, 0.4-2.0mol% of Yb2O3 and 0.1-1.0mol% of AgNO3. The tellurate glass has the following advantages that by adopting tellurium oxide as a main component and adding bismuth oxide, zinc oxide and sodium oxide, the forming ability and physical-chemical stability of the glass are improved; due to the tri-doping way of rare earth Er<3+>, Ce<3+> and Yb<3+> ions, the sensitization among the rare earth ions is sufficiently utilized to improve the luminous efficiency of the rare earth Er<3+> ions under a commercial 980nm-wavelength semiconductor laser diode pump; and the fluorescence emission intensity of the doping Er<3+> ions in the 1.55mu m near infrared waveband is enhanced by the local field enhancement effect of the silver nano particles.
