| 中文摘要 | re3+ (eu3+, tb3+) complexes with carboxylic acid (salicylic acid and benzoic acid) were introduced into the sol, which was prepared by the hydrolysis of tetraethoxysilane (teos). a sol-gel luminescent thin film (sg-ltf) was then prepared by dispersing the sol onto a silica substrate by a spin coating method. multi-layer luminescent thin films were prepared by repeating the same process. the luminescent spectra, fluorescence lifetime and thermal stability of the sg-ltfs were investigated. for the reason of comparison polyvinylbutyral (pvb) was added into a n,n-dimethylformamide (dmf) solution in which the comparative re3+ carboxylic acid complexes were previously dissolved to form the dmf/pvb solution and the pvb luminescent thin film (pvb-ltf) was prepared. the results show that a broad excitation band indicates the formation of re complexes in the solid sg-ltfs. re ions, which are restrained in the silica matrix, present longer lifetimes and higher thermal stability than that in the pvb-ltf containing the corresponding pure complexes. the different doping concentration of re (iii) complexes in the sg-ltfs and the different change of the emission intensities with the heat treatment temperature in the sol-gel thin film and the sol-gel bulk gel were also discussed in this paper. |
