本文合成了 Gd3Ga5 O1 2 :Ag材料 ;用电子束蒸发制备成交流的薄膜电致发光器件 ,采取 X光衍射的方法分析了材料的结晶度及成份 ;器件得到了较好的蓝紫色发光 ,发光峰位于 397nm和肩峰 46 7nm;通过对掺和不掺发光中心材料的吸收光谱和光致发光的研究 ,得出 397nm和 46 7nm分别来自于氧空位和 Ag+的发光。
In this paper, Gd3Ga5O1 2: Ag materials were synthesized. The thin film electroluminescent devices were prepared by electron beam evaporation. The crystallinity and composition of the materials were analyzed by X-ray diffraction. The device was blue- The peak at 397nm and the shoulder peak at 467nm. By studying the absorption spectrum and photoluminescence of the undoped luminescent center material, the luminescence of 397nm and 467nm from oxygen vacancies and Ag + were obtained respectively.
