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 N-2 adsorption). Furthermore , the surfactant was removed by calcinations, metal oxide was removed by nitric acid and porous silica material was obtained.
