A preparation method for improving light efficiency and stability of light storing ceramics is provided. Calcium ethanol solution is added into titanium precursor solution firstly and oleic acid dispersant is added, pure water and the light storing powder are subsequently added to obtain a light-storing powder-calcium titanate gel, and dried, crushed and sieved to obtain xerogel powder. Glass matrix material, sieved xerogel powder and another dispersant are placed into a granulator, and directly mechanically stirred and granulated after adding pure water. A plasticizer is added after stirring 4˜8 h, and continuously stirred for 1˜3 h to obtain a mixture, pressing, drying and firing. Calcium titanate is manually introduced to protect the light-storing powder from hydrolysis or high-temperature oxidation. It can also change the propagation path of fluorescence inside ceramics, improve light absorption and fluorescence output efficiency and is conducive to ceramic molding.
