Abstract：
 An aluminate-base fluorescent powder is prepared through proportioning its raw materials, dissolving in citric acid, maintaining at 80-98 deg.C to become sol and then gel, pre-calcining, sieving by 300 meshes, and calcining in reduction atmosphere. Its advantages are simple preparing process, high uniformity (0.1-10 microns), and low cost.
