| titleOfInvention | Preparation of cerium doped yttrium aluminum garnet fluorescent powder |
| abstract | The present invention relates to a novel process for preparing cerium doped yttrium aluminum garnet [(Y,Ce)3Al5O12 type] fluorescent fine powder. This process utilizes the metallic chelate compound/organic alkali gel method to prepare fine powders, which is different from conventional solid state reaction method. To a solution of metal oxides or nitrates having a molar ratio of Y:Ce:Al=3-x:x:5 (0<x<=0.5), a chelating agent was added to form a metallic chelat compound, and then an organic alkali was added to adjust the pH value thereof to alkaline and to form a viscous solution. The viscous solution was heated at 80-110 DEG C to form a gel followed by calcining at 1500 DEG C to form the fluorescent fine powder. |
