摘要	The upconversion of 966nm infrared radiation into visible light has been studied in 69.9 PbF2 + 7.5WO3 + 7.5TeO2 : 15YbF3 : 0.1TmF3 ceramic. Several upconversion emission bands were observed in the spectral range of 460 and 830nm. The blue and red emission bands are centered at 478 and 775nm, respectively. Intensity versus excitation power measurements confirm that the red emission was due to the two photon absorption while the blue emission was a result of three photon absorption processes. Absolute fluorescence efficiencies were determined at room temperature for 16.5mW/cm2 excitation intensity, using a comparative method. Values obtained for the red and blue emissions are 5.8 10(-2) and 7.5 10(-6), respectively in the compound prepared at 900-degrees-C. Annealing the compound at 460-degrees-C for four hours increases the upconversion efficiencies of the 478 and 775 nm emissions, about two times. Temperature dependence of these upconverted emissions was investigated for the annealed and not annealed samples.
