In order to improve the properties for application of(La,Ce,Tb)PO_4,the high-efficientcy and small particle size green-emitting phosphors(La,Ce,Tb)PO_4 were synthesized by using the sol-sedimentation,Li_2B_2O_4 as flux and adding pre-burning and post-burning process at lower temperature.
为改进(La,Ce,Tb)PO4应用特性,采用溶胶沉淀法、增加低温预烧和复烧工艺及采用助熔剂Li2B2O4等方法合成了高效磷酸盐绿色荧光粉(La0。
补充资料:碘化物热分解法
利用化学迁移反应原理,由粗金属通过碘化物热分解制取高纯金属的一种精炼方法。1925年首先由德国人范阿克耳(A.E.Van Arkel)和德布尔(J.H.de Boer)应用于钛和锆的提纯,因此也称为范阿克耳(Van Arkel)法。由于碘在过程中循环使用而不消耗,也有人称之为"催化蒸馏"(catalytic distillation)法。目前此法已成功地应用于小量高纯金属如钛、锆、铪、钒、硅、铬、铀、钍等的制取,但工业规模生产时成本较高。
