报道了一种新的Zn—Al类水滑石的荧光现象,即在没有任何荧光物质插层的情况下,Zn—Al类水滑石本身就具有荧光性质,其最大激发波长位于375nm,最大发射波长处于443nm,显示的荧光为蓝色可见光.这一光学功能的发现将有助于类水滑石在光学材料领域中的进一步应用.
A new fluorescence behavior of hydrotalcite-like compounds (HTlc) was reported, i.e., Zn-Al-HTlc itself could emit fluorescence without any fluorescent substances intercalated. Its excitation spectrum shows a maximum peak near the wavelength 375 nm, the maximum emission peak appears at 443 nm and the fluorescence color of the Zn-Al-HTlc sample is blue. This new optical property will be expected to extend the potential applications of HTlc in optical material fields.
