摘要：
Green up-conversion luminescence (UCL) of Tb3+ in SiO2 and ZnO-SiO2 glasses was observed with femtosecond (fs) laser (800 nm) excitation. The UCL mechanism of Tb3+ in both glasses contributed to the simultaneous three-photon absorption. The saturation effect of Tb3+ in SiO2 glass took place. The saturation effect of excited-state levels of Tb3+ in SiO2 glass was associated with the slower decay rate of D-5(4) level. This result implied that saturation power of Tb3+ in ZnO-SiO2 glass was higher than that in SiO2 glass.
