Electrodeposition method was used for synthesis of CdO thin films. In the experiments, 0.02 M CdCl₂ and 0.02 M Cd(NO₃)₂were used as to be an electrolyte in various volumes. As concentration of Cd(NO₃)₂increased, film thicknesses and crystallite sizes decreased. Remarkable results were observed in the optical properties of the CdO thin films. As the volume of used Cd(NO₃)₂increased, the band gap also increased from the 2.30 eV to the 2.63 proportionally. For the first time in the SEM image, the pyramidal form of CdO was observed.

电解质对电沉积CdO薄膜的影响

电沉积法用于合成CdO薄膜。在实验中，使用0.02M CdCl ₂和0.02M Cd（NO ₃）₂作为各种体积的电解质。随着Cd（NO ₃）_2的浓度增加，膜厚度和微晶尺寸减小。在CdO薄膜的光学性质上观察到了显着的结果。随着使用的Cd（NO ₃）₂的体积增加，带隙也从2.30 eV按比例增加到2.63。在SEM图像中，第一次观察到CdO呈金字塔形。
