【摘要】：采用溶胶-凝胶模板法,以二合水醋酸锌为前驱体,二乙醇胺为稳定剂,引入模板剂聚二乙醇获得多孔氧化锌薄膜。借助于扫描电镜、透射电镜、X射线衍射等手段,对薄膜的微观组织结构、生长过程和光学性能进行研究,并分析了模板剂对薄膜生长的溶胶-凝胶过程的影响。研究结果表明,加入适量模板剂后易获得多孔结构、结晶良好的薄膜。随浓度增加孔道逐渐向蠕虫状转变,孔隙率有所下降,多孔薄膜的折射率处于1.5~1.7范围,透射率可提高到95%以上,薄膜的光学性能进一步提高。
[Abstract]:Porous zinc oxide thin films were prepared by sol-gel template method with diethanolamine as stabilizer and zinc acetate dihydrate as precursor. By means of scanning electron microscope (SEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD), the microstructure, growth process and optical properties of the films were studied. The influence of the template on the sol-gel process of the films was analyzed. The results show that the films with porous structure and good crystallization are easy to be obtained by adding proper amount of template. With the increase of the concentration of the pore channel, the porosity of the film is decreased, the refractive index of the film is in the range of 1.5 ~ 1.7, the transmittance can be increased to more than 95%, and the optical properties of the film can be further improved.
