摘要
The thermal properties of 68TeO2-15BaF2-5SrF2-10LaF3-2KF glass were measured by different temperature analysis （DTA）. Up-conversion luminesceuce of Er^3＋ ion in the obtained glass was investigated. Mechanism of up-conversion emission was discussed. The result shows that the obtained oxvfluoride tellurite glass 68TeO2-15BaF2-5SrF2-10LaF3-2KF has a good thermal stability （ΔT = 153.6 ℃） and strong up-conversion green emissions around 527 nm and 549 nm and red emission at 660 nm. This glass can be a promising host material for up-conversion fiber lasers.
