摘要
Besides gas sensitivity,NASICON (Na super ion conductor) material has luminescence characterization.In this paper,the photoluminescence properties of NASICON and doped-NASICON material are investigated.The NASICON material was synthesized by conventional sol-gel process,and doped with Er_2O_3,Tm_2O_3,Dy_2O_3,CsCl by 1%,3%,5% (mass ratio),respectively.The ultraviolet light (325 nm,He-Cd laser) excited luminescent emissions of the resulted powders are recorded vs.wavelength in the 330 nm to 650 nm range.The main peak of the pure NASICON is found at the wavelength of 474 nm (blue light),the transition energy is 2.616 eV.The luminescent intensity is weakened obviously after doping with Er_2O_3 and Tm_2O_3,but is increased after doping with Dy_2O_3 and 3% CsCl.
Besides gas sensitivity, NASICON （Na super ion conductor） material has luminescence characterization. In this paper, the photoluminescence properties of NASICON and doped-NASICON material are investigated. The NASICON material was synthesized by conventional sol-gel process, and doped with Er2O3, Tm2O3, Dy2O3, CsCI by 1%, 3%, 5% （mass ratio）, respectively. The ultraviolet light （325 nm, He-Cd laser） excited luminescent emissions of the resulted powders are recorded vs. wavelength in the 330 nm to 650 nm range. The main peak of the pure NASICON is found at the wavelength of 474 nm （blue light）, the transition energy is 2.616 eV. The luminescent intensity is weakened obviously after doping with Er2O3 and Tm2O3, but is increased after doping with Dy2O3 and 3% CsCI.
