Abstract
The invention refers to quantum dots (QDs) composite particles and their preparation method, photoelectric elements and photoelectric equipment. The preparation method of QDs composite particles comprises: coating the surface of metal nanoparticles (MNPs) with silica; modifying the silica coated MNPs through amination to make the surface of the silica have amino functional groups; and combining the carboxyl-functionalized QDs with amino-functionalized silica coated MNPs, thereby preparing the QDs composite particles. The preparation method can enhance the fluorescent efficiency of QDs.
