Abstract

This invention provides a phosphatide functionizing photoluminescence enhancement type nucleocapsid structural quanta point and its preparation, which belongs to composite technique field. Its material includes metal oxide, metal and nonmetal alkyl compound, the fourth nonmetal element. The nucleocapsid structural quanta point is obtained by solution high temperature cooling crystallizing, and then the phosphatide with hydrosulfide is added, and then the bioactive phosphatide functional photoluminescence enhancement type nucleocapsid structural quanta point is produced by the reaction of metal and hydrosulfide. The experimental result shows that the functionizing of phosphatide towards nucleocapsid structural quanta point not only improves colloidal state aqueous phase stability of quanta point, but also enhances its function of photoluminescence of quanta point. The degree of its photoluminescence enhancement will be a function of the concentration of phosphatide functionizing quanta point. This invention provides a biological platform for solar battery and biosensor.

Description

technical field [0001] The invention relates to a method in the technical field of composite materials, in particular to a method for preparing phospholipid-functionalized photoluminescence-enhanced core-shell structure quantum dots. Background technique [0002] Semiconductor quantum dots are small semiconductor structures with multidimensional structures in the nanoscale range. The size and shape of these structures and the number of electrons they hold can be precisely controlled, so quantum dots exhibit many physical behaviors of quantum systems in the microscopic world. It is especially worth mentioning that quantum dots with a core-shell structure, such as cadmium selenide / zinc sulfide, cadmium telluride / zinc sulfide, cadmium sulfide / zinc sulfide, have been proven to have more stable fluorescence effects. Thanks to these special physical properties derived from the nature of quantum confinement, quantum dots have been proposed as a functional platform for novel materi...
