摘    要:平板显示是显示技术发展的方向,发光材料的薄膜化是显示技术发展的重要研究对象.本研究采用电沉积-烧结方法制备出了氧化钇铕红色荧光薄膜.在0.1 mol/L硝酸钇溶液中加入4%(摩尔分数)0.1 mol/L硝酸铕掺杂,用三电极体系进行阴极电沉积,工作电极的电位为-1.2 V(相对于Ag/AgCl电极),温度65℃,沉积时间为400 s,500℃灼烧2 h,制备出的发光薄膜与高温固相法制备的薄膜对比,其发射光谱的峰位相同.XRD检测显示经不同温度灼烧后,随温度的升高,氧化钇晶相逐渐完整.经SEM扫描,薄膜沉积均匀平整.

关 键 词:电沉积-烧结法  薄膜  氧化钇铕  荧光

Abstract:The flat panel display is the development direction of display technology.Filming luminescence material possess important position in display technology.In this paper,electrochemical deposition of red luminescent Y_2O_3∶Eu thin films on transparent conducting optically(ITO) glass substrates by cathodic reduction of yttrium nitric has been investigated.Y(OH)_3 deposits were obtained using a conventional three electrode cell that potential of work electrode was-1.2 V vs.Ag/AgCl electrode for 400 s in a 0.1 mol/L Y(NO)_3,with 4%(mol/mol) Eu(NO)_3,temperature 65 ℃.Then the glass coated Y(OH)_3 containing Eu sintered for 2 h at 500 ℃.The luminescence spectrum of film preparated by this method was similar compared with that of the powder preparated by solid methed.XRD confirms the formation of Y_2O_3 and SEM reveal uniformity of film.
Keywords:electrodeposition-sinter method  film  Y_2O_3∶Eu   luminescence
