摘要：

Optical spectroscopy of Tm3+-doped 59H(3)BO(3)-20ZnO-20LiF-1Tm(2)O(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 (D-1(2) --> F-3(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. (C) 2004 Elsevier B.V.
