Hydrothermal Synthesis and Characterization of Flowerlike YBO3:Eu3+
Source abstract
Abstract
采用水热法制备了均匀分散、具有花球形貌的YBO3∶Eu3＋. 利用X射线衍射仪、X射线能量仪、高分辨透射电镜、扫描电镜等手段对其结构、形貌进行了研究, 发现其为六方球霰石晶相, 仅含有Y、O、B、Eu元素, 微球直径约1~2μm, 组装成花球的薄片厚度约100nm. 提出了其形成机理：在水热过程中生成的YBO3晶核在六亚甲基四胺（HMT）的调节下各向异性生长为二维薄片, 并最终组装成为花球状结构. 研究发现得到的YBO3∶Eu3＋在612nm表现出显著的红光发射, 并且由于Eu3＋附近晶体场对称性降低, 样品表现出较高的红光/橙光（R/O）比率.
