Luminescent microspheres and a preparation method thereof are disclosed. The preparation method includes: 1) preparing cadmium oxide-doped silica microspheres; 2) adding the silica microspheres to a mixed solution of octadecene/oleic acid or trioctylamine (TOA)/oleic acid, and heating a resulting mixture to a boiling point so that the microspheres swell at high temperature and the oleic acid penetrates into the microspheres to react with CdO to obtain an organic cadmium-adsorbed silica suspension; and 3) adding a selenium precursor to the obtained organic cadmium-adsorbed silica suspension to obtain the luminescent microspheres, where, the selenium precursor reacts with the adsorbed organic cadmium to form CdSe. The luminescent microspheres provided in the present disclosure have high fluorescence efficiency and prominent stability, require no barrier materials such as barrier films for protection, and can be directly used for light conversion materials with high color gamut such as luminescent films, luminescent plates, Mini-LEDs, and Micro-LEDs.
