摘要

Optical spectroscopy of Tm~(3+)-doped 59H_3BO_3-20ZnO-20LiF-1Tm_2O_3 glass is presented. From the measured absorption spectra, radiative parameters were determined using the Judd-Ofelt (JO) theory. Excitation in the range of 750-800 nm resulted in a frequency up-converted emission at 453 nm (~1D_2 -- > ~3F_4). Excitation spectra and intensity dependence of the up-converted fluorescence have been investigated and a mechanism has been proposed that explains up-conversion process.
