Microwave Hydrothermal Synthesis of Hexagonal NaYF4 and Yb3+,Er3+-doped NaYF4 Microtubes
Source abstract
Abstract
为了合成单相以及Yb3＋、Er3＋掺杂的六方结构NaYF4,采用微波水热的方法,以稀土硝酸盐、氟化钠、柠檬酸、氢氧化钠、乙酸乙酯和水为原料,合成了六方相NaYF4以及Yb3＋、Er3＋掺杂的六方相NaYF4（NaYF4∶Yb3＋,Er3＋）微米管.利用XRD、SEM对所得样品的物相和形貌进行了表征.研究了不同反应条件对产物形貌和物相的影响,并提出了NaYF4微米管的形成机理.研究发现,采用微波加热的方法可以在较低的温度下快速得到单一六方相的NaYF4.所制备的Yb3＋、Er3＋掺杂NaYF4微米管的上转换发光性能与其体材料类似,具有较高的发光强度.
