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.
