摘要

Tm3+ activated germanate-tellurite glasses with good thermal stability and anti-crystallization ability were prepared. Efficient 2 gm fluorescence was observed in the optimal concentration Tm3+ doped glass and the corresponding radiative properties were investigated. For Tm3+: F-3(4) -> H-3(6) transition, high spontaneous radiative transition probability (260.75 s(-1)) and large emission cross section (7.66 x 10(-21) cm(2)) were obtained from the prepared glass. According to Dexter's and Forster's theory, energy transfer microscopic parameters were computed to elucidate the observed 2 mu m emissions in detail. Besides, the effect of hydroxy groups quenching was also quantificationally investigated'based on simplified rate equations. Results demonstrate that the optimal concentration Tm3+ doped germanatetellurite glass possessing excellent spectroscopic properties might be an attractive candidate for 2 mu m laser or amplifier.
