英文摘要	通过溶胶凝胶技术制备了掺Eu3 + 的硅基材料并测试了其三维荧光光谱、激发光谱和发射光谱 ,结果显示 :最佳激发波长为 35 0nm ,最强荧光波长为 6 10nm ;在 35 0nm光激发下的发射光谱显示Eu3 + 的特征发射光谱 ,产生 4条谱带 ,分别是 5 77nm ( 5D0 7F0 ) ,5 88nm ( 5D0 7F1) ,5 96nm( 5D0 7F1)和 6 10nm ( 5D0 7F2 )。; Eu3+-doped silica material was synthesized using sol-gel process. The fluorescence spectrum of Eu3+ was investigated. Three-dimensional fluorescence spectra showed that the optimum excitation wavelength was 350 nm, the strongest emission wavelength was 610 nm. At room temperature, emission spectrum excited by 350 nm showed four characteristic emission peaks at 577 nm (D-5(0)-F-7(0)), 588 nm (D-5(0)-F-7(1)),596 nm (D-5(0)-F-7(1)),610 nm (D-5(0)-7F(2)) and the corresponding excitation spectra peaks at 318, 362, 380, 393, 412 nm, respectively. These results illustrate that the luminescent emission from doped-Eu3+ silica material have spectral characteristic type of radiation transition among the electronic energy levels associated with the 3(+) ionized state of europium, and luminescence properties of Eu3+ are strongly related to his chemical and structural environemt.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000175286800028&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 6; 02; 270-272; 22
