Abstract
Red light-emitting fluorescent hydrotalcite-like compound was synthesized by coprecipitation method,and then surface-modified using silane coupling agent. The composition and structure of the resulted compound was characterized by fluorescence spectroscopy,Fourier transform infrared(FTIR) spectroscopy,X-ray diffraction(XRD),scanning electron microscopy(SEM),etc. The influence of surface modification was discussed. Additionally,A light-emitting diode(LED) was fabricated by coating hydrotalcite-like compound onto In Ga N-based LED chip that emits 384 nm light. The device emits bright red light. The results indicate that red light-emitting fluorescent hydrotalcite-like compound can act as red components in the fabrication of white LED.
