摘要
我们报导纯 Co-Al-layered 双氢氧化物(LDH ) 的新光行为。没有任何荧光灯的物质， Co-Al-LDH 样品能射出荧光，这被发现设置。它的刺激光谱在波长附近显示出一座最大的山峰 370 nm，最大的排放山峰在 430 nm 出现， Co-Al-LDH 样品的光致发光颜色是蓝的。这个新光性质将被期望在光材料地里扩大 LDH 的潜在的应用。
We report a new optical behaviour of pure Co-Al-layered double hydroxide （LDH）. It was found that the Co-Al-LDH sample could emit fluorescence without any fluorescent substances intercalated. Its excitation spectrum shows a maximum peak near the wavelength 370 nm, the maximum emission peak appears at 430 um and the photoluminescence colour of the Co-Al-LDH sample is blue. This new optical property will be expected to extend the potential applications of LDHs in optical materials field.
