摘要：

A fluoroaluminozirconate glass was compared with a fluorozirconate and a fluoroaluminate glass as a host material for upconversion emissions in a Ho3+ -Yb3+-codoped system. The green emission of 543 nm is 50% stronger in fluoroaluminozirconate than in fluorozirconate. This is because the emission is primarily governed by the Yb3+ -Ho3+ energy-transfer rate rather than by the multiphonon decay rate of the emitting level. The optimum concentrations of Ho3+ and 2Yb3+ ions for emission intensity are 0.2 and 3.0 cationic %, respectively, at a pumping density of 560 W/mm2. By tuning a pump wavelength we also observed intense UV-blue upconversion emissions from the fluoroaluminozirconate fiber sample.
