| titleOfInvention | A kind of preparation method of the dendritic europium doping lanthanum hydroxycarbonate red fluorescence powder of triangle |
| abstract | A kind of preparation method of the dendritic europium doping lanthanum hydroxycarbonate red fluorescence powder of triangle disclosed by the invention, comprises the following steps：A) lanthanum salt and rare-earth europium salt are dissolved in mixing liquid and the stirring of diglycol and water；B) mixing liquid described in one side whipping step a) is while add urea and polyvinylpyrrolidone, until urea is completely dissolved to obtain colourless transparent liquid；C) colourless transparent liquid described in step b) is transferred under autoclave and reacted, obtain the europium doping dendritic lanthanum hydroxycarbonate of triangle.The method of the invention has the advantages that：(1) cost of material is low, synthesis technique is simple, product quality is stable and process repeatability can be good；(2) can extensive industrialization；(3) the strong red emission of product.Product prepared by methods described can be widely applied to agricultural film light conversion agent, PDP, LED fluorescent material and other high-tech areas. |
