In this work, a facile spray-assisted perfume atomizer technique was used to prepare CdO and Fe-doped CdO (CdO:Fe) thin films with varying concentrations of Fe (1, 3, and 5 wt%). The deposited films were characterized using different analytical techniques to realize the structural, morphological, optical, electrical, and photosensing properties. From X-ray diffraction (XRD) results, the CdO and CdO:Fe thin films have a cubic structure and an increase in crystallite size was observed for the CdO:Fe(3%) sample. The optical studies of the doped samples reveal a high absorption in the observed wavelength range and a decrease in optical bandgap values. The CdO:Fe(3%) sample exhibits a minimum resistivity value (4.02 × 10^–3 Ωcm), high carrier concentration (22.92 × 10¹⁹ cm⁻³), and high mobility (6.78 cmV⁻¹ s⁻¹). The current–voltage characteristics suggest that the CdO:Fe(3%) sample has a lower ideality factor of 4.2, high photocurrent value of 1.62 × 10^–2 A. It also has better photosensing parameter values such as responsivity of 0.15AW⁻¹, the external quantum efficiency of 2.92 × 10⁸ Jones, and detectivity of 50%, which are due to the synergistic effect of increased crystallite size, high light absorption, optimum bandgap, and better electrical properties of the CdO:Fe(3%) sample.

在这项工作中，一种简便的喷雾辅助香水雾化器技术用于制备具有不同 Fe 浓度（1、3 和 5 wt%）的 CdO 和 Fe 掺杂的 CdO（CdO:Fe）薄膜。使用不同的分析技术对沉积的薄膜进行表征，以实现结构、形态、光学、电学和光敏特性。根据 X 射线衍射 (XRD) 结果，CdO 和 CdO:Fe 薄膜具有立方结构，并且观察到 CdO:Fe(3%) 样品的微晶尺寸增加。掺杂样品的光学研究表明在观察到的波长范围内有高吸收和光学带隙值的降低。CdO:Fe(3%) 样品表现出最小电阻率值 (4.02 × 10 ^–3 Ωcm)、高载流子浓度 (22.92 × 10 ¹⁹  cm ^-3) 和高迁移率 (6.78 cmV ^-1  s ^-1 )。电流-电压特性表明，CdO:Fe(3%) 样品的理想因子较低，为 4.2，光电流值为 1.62 × 10 ^–2 A。它还具有更好的光敏参数值，例如响应度为 0.15AW ^-1 , 外量子效率为 2.92 × 10 ⁸ Jones，探测率为 50%，这是由于 CdO:Fe(3%) 的晶粒尺寸增大、高光吸收、最佳带隙和更好的电性能的协同作用样本。
