| titleOfInvention | Preparation method of yttrium aluminum garnet yellow fluorescent powder for white light LED |
| abstract | The invention relates to a preparation method of yttrium aluminum garnet yellow fluorescent powder for white light LED (light-emitting diode). The method comprises the steps of: according to a stoichiometric ratio of each metallic element in Y3-x-yGdxAl5O12: yCe<3+>, preparing a mixed nitrate solution of metals contained in a target product; adding a soluble salt, an organic fuel and ammonium nitrate, heating the solution for dissolution till approximately a sticky state, conducting microwave irradiation so as to initiate self-propagating combustion; carrying out washing, drying, grinding and sieving, thus obtaining the yttrium aluminum garnet yellow fluorescent powder of a necessary particle size. The yttrium aluminum garnet yellow fluorescent powder prepared in the invention has controllable particle size, uniform size, regular appearance, and excellent light-emitting performance, and has the advantages of convenient implementation, simple equipment, short synthesis time, no need for long-time material mixing, high-temperature calcination, and ball-milling crushing. Therefore, the preparation method of the invention is a rapid and energy-saving new method for controlling the synthesis of yttrium aluminum garnet yellow fluorescent powder of different particle sizes. |
