摘要：
A detailed study of the spectroscopic properties of the PbF2 + GeO2 + WO3:YbF3, TmF3 glass ceramics under infrared excitation (966 nm) has been investigated. The emission, excitation spectra, luminescence decay times and up-conversion efficiency were measured. The up-conversion of infrared into violet (363 nm), blue (451 and 478 nm) and red (680, 698 and 779 nm) was observed for TM3+ ions in the sample. By a comparative method, an absolute fluorescence efficiencies of 10(-6) and 5.86 x 10(-3) have been obtained for dominant blue (478 nm) and red (779 nm) up-conversion when the sample is excited by 966 nm light with an absorbed intensity of 16.5 mW/cm2 at room temperature.
