摘要:

通过共沉淀法合成了发红色荧光的类水滑石材料, 采用硅烷偶联剂对其进行了表面改性, 并利用荧光光谱、 红外光谱、 X射线衍射(XRD)和扫描电子显微镜(SEM)等对其结构和性能进行了表征, 探讨了表面改性对荧光类水滑石的影响. 将改性荧光类水滑石与发射波长为384 nm的InGaN芯片组合制成发光二极管, 器件发出明亮的红光. 研究结果表明, 改性的发红色荧光的类水滑石是制作白光二极管可供选用的红色发光材料.

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 InGaN-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.

Key words: Light-emitting diode(LED), Hydrotalcite-like compound, Rare earth complex, Silane coupling agent
