摘要

利用水合肼作缓释型碱源和络合剂

采用水热法合成了Zn

SnO

立方多面体。XRD物相分析表明

产物为结晶良好的立方反尖晶石结构Zn

SnO

。FESEM和TEM形貌分析表明

该Zn

SnO

微晶为边长100~400 nm左右的立方体

其光致发光光谱是蓝-绿光发射带(中心590 nm处)

在400 ℃空气气氛下退火1 h后

蓝-绿光发射带的强度显著降低。这主要是因为退火处理提高了晶体质量

降低了氧空位浓度

从而降低了可见光发射带的强度。

Abstract

SnO

nanocubes have been synthesized via a simple and facile one-pot hydrothermal process. The X-ray diffraction (XRD) pattern demonstrates that the products are fine single crystals Zn

SnO

with the inverse spinel crystal structure. The FESEM and TEM images confirm that Zn

SnO

microcrystallines are cube-like structure with the side length of 100~400 nm. In addition

the photoluminescence (PL) spectra of Zn

SnO

nanocubes at room temperature show a broad blue-green emission around the 380~820 nm wavelengths with a maximum center at 590 nm. The PL property of the Zn

SnO

nanocubes can be obviously reduced by annealing at 400 ℃ for 1 h due to the improvement of the crystal quality and the reduced concentration of oxygen vacancy.
