中文摘要：
采用溶胶-凝胶法合成了SiO2：Eu^3＋玻璃，以Eu^3＋作为荧光探针研究了飞秒激光辐照所诱导的荧光变化。结果表明：经飞秒激光辐照后，Eu^3＋的电荷迁移吸收的相对强度明显降低；辐照后的低温^7F0-^5D0激发峰发生蓝移，表明飞秒激光辐照诱导Eu^3＋周围的微观环境发生变化。低温荧光谱线窄化光谱进一步证明飞秒激光辐照诱导了Eu^3＋周围的微结构发生变化。
英文摘要：
Eu^3＋ doped SiO2 silicate glasses were prepared by sol-gel method, The fluorescence changes of Eu^3＋ induced by femto- second laser were investigated. The results indicate that the relative intensity of the charge transfer band decreases after ferntosecond laser irradiation. The ^7F0-^5D0 transition absorption blue-shifted in irradiated glass, indicates that the local environments surrounding the Eu^3＋ ions greatly change because of irradiation. Fluorescence narrow spectra further confirms this result,
