摘要: 采用水热合成技术将表面修饰有羧基的纳米CdTe微粒与表面活性剂和硅源进行自组装,得到了一种与氧化硅复合的稳定的CdTe发光材料.通过一系列表征手段(如TG-DTA,EDX,TEM,荧光光谱和N2吸附)证实了CdTe微粒复合在氧化硅中.进一步通过烧结的方法除去表面活性剂,用稀酸除去金属氧化物,即得到多孔的氧化硅材料.

Abstract: A kind of stable fluorescence CdTe nanostructure material encapsulated by silica has been synthesized hydrothermally from the assembling of nanosized CdTe particles, surfactant and silicon source, and this composite nanostructure was characterized by means of a series of techniques(such as TG DTA, EDX, TEM, fluorescence spectra and N2 adsorption). Furthermore, the surfactant was removed by calcinations, metal oxide was removed by nitric acid and porous silica material was obtained.

Key words: Hydrothermal synthesis, Nanosized CdTe particles, Self assemble
