| titleOfInvention | Red phosphor powder for white LED as well as preparation method and application thereof |
| abstract | The invention relates to red phosphor powder for an LED, having a general chemical composition formula of ALn1-xNb2O7: xEu3+, wherein A comprises one or more than two of Li, Na, K or Rb, Ln comprises one or two of Gd or Y, and x is not smaller than 0.10 and is not larger than 1.00. The preparation method of the red phosphor powder for the white LED comprises the following steps of: (1) weighting, grinding and evenly mixing the raw materials according to the mol ratio of the ALn1-xNb2O7: xEu3+; (2) putting a mixture in the step (1) in air atmosphere of a muffle furnace to roast at 1000-1600 DEG C for 3-15h; and (3) post-treating the roasted product obtained in the step (2). The phosphor powder of the invention can be effectively excited by near-ultraviolet light and blue light to emit red light, can be favorably matched with near-ultraviolet light and blue light LED chips, has stable physical and chemical properties, avoids reactions with oxygen, water, carbon dioxide, and the like in environment and resists heat without toxicity or pollution nuisance. The preparation method is simple and easy to operate for directly roasting in air and has favorable application prospects. |
