| Abstract: | The Eu3+ ion doped SiO2 aerogel thi n film were prepared by sol-gel process. The surface structure of fil m were observed by AFM. The excitation, emission, and time-resolved spec tra were measured. The time-resolved spectra show that the emission f rom 5D1 were decay, while the ones from 5D0 show a increasing process in decay process. The luminescent dynamics were discussed to explain these decay process, and the solutions obtained can by compare d to the computer simulation with the experimental results. |
