【摘要】 用低温扩散锰离子的方法,制作了较高亮度的电致发光材料。材料的晶体结构由X射线衍射分析,实验结果表明:当扩散温度低于800℃时,晶体的六角相结构趋于零,只有立方相结构。用低温扩散法可以获得较高亮度的橙色电致发光材料。更多还原

【Abstract】 The orange ZnS∶Mn,Cu electroluminescent phosphors are obtained with manganese ions diffusion at low temperature. The lattice structure of ZnS∶Mn,Cu phosphors is determined with X-ray analysis. It shows that hexagonal structure decreases to zero at the temperature of diffusion as low as 800 ℃ and the brightness becomes higher.更多还原
