| 摘 要： | 本文通过水热法合成了含有3种不同稀土离子的层状稀土氢氧化物(Gd0.5Tb0.5-xEux)2(OH)5NO3.nH2O,并选择有机物水杨酸(HSA)作为敏化剂,通过在水热条件下的离子交换反应,成功将其以有机阴离子形式与层状稀土氢氧化物插层组装获得有机-无机杂化荧光材料(SA--LRHs∶xEu)。荧光性质测定表明,SA-通过有效的能量转移增强了Tb3+的特征绿色荧光发射,随着Eu3+含量的增加,Eu3+的特征红色荧光发射随之增强,而Tb3+的特征绿色荧光发射随之减弱。在此基础上,将发光颜色可调的有机-无机荧光材料与聚甲基丙烯酸甲酯(PMMA)复合组装出透明的荧光薄膜。

| Abstract: | Herein, the organic-inorganic hybrid phosphors has been designed and assembled by the intercalation of salicylic acid (HSA), as sensitizer, into the layered rare-earth hydroxides (LRHs) with the compositions of (Gd0.5Tb0.5-xEux)2(OH)5NO3·nH2O, through ion-exchange reaction under hydrothermal condition. More interestingly, the luminescence color of the SA--LRHs:xEu can be easily tuned from green to red due to the energy transfer from the Tb3+ to Eu3+ ions by changing the doping concentration of activator ions. In addition, the transparent and color-tunable luminescent film devices can be fabricated facilely with the use of SA--LRHs:xEu hybrids and polymethyl methacrylate (PMMA). |
