为了得到无团聚的球形荧光粉颗粒以提高其物理和光学性能,以尿素为前驱体溶液中的添加剂,合成了等离子显示用(Y,Gd)BO3:Eu红色荧光粉。在喷雾热解过程中,通过前驱体溶液的性质来控制颗粒形貌,改善荧光粉的光学性能。获得的结果表明,前驱体溶液中加入尿素成分,能够影响颗粒形成过程、改善颗粒表面状态,从而可以促使最终产物具有良好的形貌和优异的发光强度。 In order to obtain non-agglomerated spherical phosphor particles to improve their physical and optical properties, a (Y, Gd) BO3: Eu red phosphor for plasma display was synthesized by using urea as the additive in the precursor solution. During spray pyrolysis, the particle morphology is controlled by the nature of the precursor solution to improve the optical properties of the phosphor. The results obtained show that adding the urea component to the precursor solution can affect the particle formation process and improve the surface state of the particles so as to promote good morphology and excellent luminous intensity of the final product.
