The simple, economical, eco-friendly sol–gel screen printing mechanism is used to incorporate pure and different zinc- (2, 4, 6, 8%) doped cadmium oxide films on glass substrate at 500 °C calcination temperature. X-ray diffraction (XRD) pattern of prepared films supports the polycrystalline and cubical nature of prepared films. High intensity peak is available at (111) plane for all prepared films. The average crystallite size and strain have been calculated by Williamson–Hall method for all films. The scanning electron microscope (SEM) confirms the impact of zinc on structural morphology of cadmium oxide films. Cd, Zn, O, and absence of any kind of impurities in prepared films has been confirmed by EDAX. It also supports the decrease in atomic percentage of Cd and O with an increase in zinc doping. UV–visible spectroscopy (300–900 nm) of prepared films confirms that the transmittance of films increases up to 60% with 6% doping of zinc and with 8% doping of zinc it decreases. It is also observed that the bandgap first increases up to 2.62 eV on varying doping of zinc from 0 to 6% and then decreases with 8% doping of zinc which clearly shows that the optical properties of cadmium oxide films enhances with doping of zinc. Photoluminescence spectrum of films confirms that there is an enhancement in luminescence property with zinc doping. Fourier transform infrared spectroscopy (FTIR) confirms the presence of Cd–O and O–C–O vibrations in films. Two-probe method has been used for the study of electrical properties of prepared films and it is seen that the electrical resistivity decreases with increase in doping of zinc up to 6% and with 8% doping of zinc it increases.

简单，经济，环保的溶胶-凝胶丝网印刷机理用于在500°C的煅烧温度下在玻璃基板上掺入纯净的和不同的锌（2、4、6、8％）掺杂的氧化镉薄膜。制备的膜的X射线衍射（XRD）图支持制备的膜的多晶和立方性质。对于所有准备好的薄膜，在（111）平面上都可以看到高强度的峰。通过Williamson-Hall方法计算了所有薄膜的平均微晶尺寸和应变。扫描电子显微镜（SEM）证实了锌对氧化镉膜结构形态的影响。EDAX已确认制备的膜中Cd，Zn，O和任何类型的杂质均不存在。它还支持随着锌掺杂的增加而降低Cd和O的原子百分比。制备的薄膜的紫外-可见光谱（300-900 nm）证实，掺杂6％的锌和8％掺杂的锌，薄膜的透射率最多可提高60％。还观察到，当锌的掺杂量从0变化至6％时，带隙首先增加至2.62 eV，然后随着锌的掺杂量的8％而减小，这清楚地表明氧化镉膜的光学性质随锌的掺杂而增强。薄膜的光致发光光谱证实，掺杂锌可以增强发光性能。傅里叶变换红外光谱（FTIR）证实了薄膜中存在Cd–O和O–C–O振动。
