摘要

本文通过水热法成功地制备出Eu3+掺杂ZnO(Eu/ZnO)材料

并研究了前驱体溶液的pH值对Eu/ZnO发光性能的影响.实验表明Eu3+离子的引入会降低ZnO样品的结晶度

且能有效地降低ZnO的禁带宽度.由PL光谱可以观察到用325 nm的紫光能有效地激发Eu3+离子的红光发射

Eu3+和ZnO之间可以实现有效的能量转移.当前驱体溶液的pH值为5时

Eu/ZnO有很强的Eu3+离子的红光发射;当溶液的pH值大于7时

则不能得到Eu3+离子的红光发射.因此

前驱体溶液的酸碱性对Eu/ZnO材料的发光性能有很大的影响

通过调整前驱体溶液的pH值可以获得白光发射.这项研究为ZnO基质的白光发射材料研究打下了一定的基础.

Abstract

Eu3+doped ZnO(Eu/ZnO) were successfully prepared by hydrothermal method

and the in?uence of the pH value of the precursor solution on the photoluminescence(PL) performance of Eu/ZnO was studied.Experiments show that the introduction of Eu3+ions can reduce the crystallinity of ZnO samples and the band gap of ZnO. Efficient energy transfer can be achieved between the ZnO and Eu3+ions

and violet light at 325 nm can effectively stimulate the Eu3+ions in the red light emission. Eu/ZnO has a strong red light emission of the Eu3+ions when the pH of the precursor solution is 5

while red light emission of the Eu3+ions cannot be get when the solution p H value is over 7

which means the PL properties of Eu/ZnO have been great in?uence by the pH values of precursor solution. So white light emission can be obtained by adjusting the pH of the precursor solution and this study has a foundation for the research of white light emitting materials of ZnO.
