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.

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 Y2O3: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 Y2O3 and SEM reveal uniformity of film.
