| titleOfInvention | Fluorescent material and preparation method thereof |
| abstract | The invention provides a fluorescent material having a specific chemical formula of Cel-xAl3(BO3)4:xLn, wherein x is not less than 0.005 and not more than 0.3, and Ln is one or two of Tb and Dy. The invention also provides a method for preparing the fluorescent material, comprising the following steps of: (1) weighing raw materials of corresponding compounds according to a stoichiometric ratio of the composition of the chemical formula; (2) sufficiently mixing the raw materials after the raw materials are ground or ball-milled; (3) carrying out first high temperature sintering on the mixed material; and (4) grinding the material obtained by the first high temperature sintering, carrying out second high temperature sintering, and cooling to obtain the fluorescent material. The preparation method disclosed by the invention comprises two reaction processes of oxidized sintering and reduced sintering, is beneficial to dispersions of rare earth activator ions in a matrix material and is easy for crystals of the fluorescent material to grow up. The fluorescent material prepared by adopting the method has the characteristics of high stability, high excited photoluminescence efficiency and the like. |
