摘要

在PVA溶液中制备ZnO:Cu纳米粉体的前驱体

经过煅烧获得ZnO:Cu纳米粉体

考察煅烧温度对制备过程及发光性能的影响。利用XRD、 TEM分析了产物的结构和形貌

XRD分析结果表明

当煅烧温度高于500℃时

可以使PVA完全分解

制备出具有六角纤锌矿结构的ZnO:Cu粉体。TEM结果表明

粉体呈球形

大小均匀

分散性好

平均粒径为20~25 nm。在342 nm波长光的激发下

在ZnO:Cu的室温PL光谱中可以观察到两个中心波长位于458 nm和486 nm的较强的蓝光发射峰

经400℃煅烧处理的ZnO:Cu纳米粉体的蓝光发射最强。煅烧后的ZnO:Cu只有微弱的绿光发射(510~530 nm)

Cu的掺杂使ZnO的绿光发射变为蓝光发射。蓝紫光的发射波长随煅烧温度的升高产生明显的红移

由300℃时的404 nm红移至600℃时的422 nm

发射强度随温度升高先增大后减小。

Abstract

The precursors of ZnO:Cu nano-powder were prepared in PVA aqueous solution. Then the products were obtained by calcining with different temperature. The effect of calcination tempe-rature on preparation and the photoluminescence of the ZnO:Cu nano-powder was investigated. The products dealed with different temperature were characterized by XRD

TEM and PL. The results of XRD indicated that when the clacination temperature was above 500℃

the products had a crystal structure of hexagonal wurtzite

while the polymer PVA decomposed completely. The TEM result showed that the nano-powder was spherical with a uniform size of 20~25 nm and good dispersibility. Two blue emission peaks centered at 458 nm and 486 nm were observed in the room temperature PL spectra excited with 342 nm light. The product calcined in 400℃ had the most strongest blue emission

while the green emissions (510~530 nm) became weak and changed into blue emission. With the clacination temperature increasing

the violet-blue spectral had an obvious red shift from 404 nm to 422 nm. The emission intensity increased firstly and then decreased.
