Mesoporous phosphor nucleocapsid preparation, and a liquid phase

The present invention provides a method of preparing mesoporous liquid core-shell phosphor. (1) generated by coprecipitation nanocrystalline yttrium oxide precursor fluoro; (2) after calcining in air-fluoro yttria YOF: Ln, and sol-gel method in YOF: Ln surface coating mesoporous silica core-shell structure is formed YOF: Ln @ mSiO2. The present invention, by using a simple, high yield method for generating a coprecipitate having a good conversion Fluorescence nanocrystalline yttrium oxyfluoride. By a sol-gel process fluorine mesoporous silica coated yttrium oxide surface, thereby forming a mesoporous structure may be drug-carrying.
