摘要

在室温离子液体1-丁基-3-甲基咪唑六氟磷酸(BmimPF6)中，通过超声辐照成功制备了铕(III)掺杂氧化锌纳米颗粒。采用XRD和TEM技术对掺杂纳米晶样品进行了表征。提出了一种可能的机制来解释Eu3+掺杂ZnO纳米材料的形成。此外，在ZnO吸收区激发后可以发现Eu3+的特征发射，表明掺杂样品发生了从ZnO到Eu3+的有效能量转移。

Preparation of europium (III) doped nanocrystalline zinc oxide in ionic liquid via an ultrasonic irradiation

In this work, europium (III) doped zinc oxide nanoparitcles have been successfully prepared in room temperature ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate (BmimPF6) via an ultrasonic irradiation. The doped nanocrystalline sample has been characterized by XRD and TEM techniques. A possible mechanism is proposed to explain the formation of Eu3+ doped ZnO nanomateirals. Additionally, the characteristic emissions of Eu3+ can be found upon excitation in the region of ZnO absorption, indicating that an efficient energy transfer from ZnO to Eu3+ occurs for the doped sample.
