摘要

气凝胶(aerogels)是一种新型的轻质纳米多孔性非晶材料,其孔洞率高达80～90%,孔洞的典型尺寸为1～100nm.已有文献报道利用SiO,2,气凝胶的纳米网络结构制备出以纳米气凝胶为骨架的纳米材料,[1～2],.通过溶胶-凝胶方法制得了Eu,3+,掺杂SiO,2,气凝胶薄膜样品,通过原子力显微镜对样品的型貌结构做了观测,测量了样品的激发-发射光谱及时间分辨光谱,研究了发光的动力学过程.

Abstract

Eu,3+, doped SiO,2, aerogel film were prepared by sol-gel process. The surface structure was observed by AFM. Excitation,emission and time resolved spectra were measured. The time resolved spectra show that the emission from ,5,D,1, was decay, while the ones from ,5,D,0, show a increasing process in decay process. Luminescent dynamic equations were setup to explain these decay process.
