摘要

以氯化锌、醋酸锌和硝酸锌为前驱体，采用喷雾热解法成功合成了ZnO薄膜。在350℃下在玻璃基板上进行薄膜沉积◦C.通过X射线衍射（XRD）研究了ZnO膜的结构性质，证实所有前驱体都具有六方纤锌矿结构。所获得的膜沿着优先（002）晶面取向。相纯度也通过X射线光电子能谱（XPS）、紫外可见光谱和能量分散X射线光谱测量（EDX）得到证实。光学测量表明，薄膜对氯化锌、乙酸锌和硝酸锌的平均透射率分别为58%、78%和65%。对于使用乙酸锌、氯化锌和硝酸锌前体的ZnO膜，获得的带隙值分别为3.19、3.17和3.23eV。此外，还对所有前驱体的ZnO薄膜的折射率和消光系数进行了探索。

Physical properties of spray pyrolysed ZnO thin films obtained from nitrate, acetate and chloride precursors: Comparative study for Solar Cell Applications

ZnO thin films prepared using zinc chloride, zinc acetate and zinc nitrate precursors have been successfully synthesized by Spray Pyrolysis method. Films depositions were carried out on glass substrates at 350◦C. Structural properties of ZnO films were investigated by X-ray diffraction (XRD), confirming that all precursors have an Hexagonal Wurtzite structure. The obtained films were oriented along the preferential (002) crystallographic plane. The phase purity was also confirmed by X-ray photoelectron spectroscopy (XPS), Ultra Violet-Visible, and Energy Dispersive X-ray spectroscopy measurements (EDX). The optical measurement revealed that films have average transmittance of 58%, 78% and 65% for zinc chloride, zinc acetate and zinc nitrate, respectively. The band gap values obtained are 3.19, 3.17 and 3.23 eV for ZnO films using zinc acetate, zinc chloride and zinc nitrate precursors, respectively. Additionally, the refractive index and extinction coefficient of the ZnO films for all precursors have been explored.
