摘要：
Oxy-fluoride glasses with composition of 25SiO(2)-65PbF(2)-9.4AlF(3)-0.1HoF(3)-0.5YbF(3) were prepared. Their upconversion fluorescence characteristics were investigated by 980 nm laser. Two emission peaks were observed at 540 and 650 nm. The up-conversion mechanism and processes were analyzed. The relationship between pumping power and relative intensity of emissions was discussed. From the dependence, it is known that the emissions centered at 540 and 650 nm are both attributed to two-photon process.
