SiO2气凝胶薄膜中Eu3+离子的跃迁
Transition of Eu3+ Ion in SiO2 Aerogel Thin Film
摘要
Abstract
The Eu3+ ion doped SiO2 aerogel film was prepared by a sol-gel process, and the luminescence and transitions of this aerogel film were investigated. The urface structure of the film was observed by AFM. Its microstructure was investigated by XRD and IR. Its excitation, emission, absorption, and time-resolved spectra were measured. The luminescence properties were discussed. The radiative transition probabilities of 5D0 energy levels in Eu3+ ion were calculated by Judd-Ofelt theory. According to the time-resolved spectra, the nonradiative transition probabilities and decay properties of 5D1 were also studied. The results are not quite different to Eu3+ ion in silicate glass, but a fine thin film doped with rare earth ionscan be obtained by using a facile and low temperature method, and this film, having luminescent light glass qualities, can possess potential applications.关键词
