摘要

采用喷雾热解法制备了钐掺杂ZnO (Sm:ZnO)薄膜。对Sm:ZnO薄膜在空气(环境)、氧气和氮气等不同气氛下进行了退火。采用x射线衍射(XRD)、扫描电镜(SEM)、拉曼光谱(Raman spectroscopy)、紫外可见光谱(UV-visible)和光致发光(PL)等技术对制备的Sm:ZnO薄膜进行了表征。Raman光谱和XRD研究证实了Sm:ZnO薄膜的纤锌矿结构。PL研究表明,其发射光谱较宽,包括紫外至黄绿色(可见)区域。

Optical properties of samarium doped ZnO thin films
Samarium doped ZnO (Sm:ZnO) thin films were deposited onto glass substrates by spray pyrolysis. The Sm:ZnO thin films were annealed in various atmosphere such as air (ambient), oxygen and nitrogen. A number of techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, UV-visible and photoluminescence (PL) were used to characterize the obtained Sm:ZnO thin films. Raman spectroscopy and XRD studies were conform wurzite structure of Sm:ZnO thin films. PL studies shown that the broad emission spectra, which includes UV to green-yellow (visible) region.
