In the present study, aluminium doped cadmium oxide (Cd_1-xAl_xO) nanoparticles at (x = 0.00, 0.03, 0.05 & 0.07) concentrations were prepared using solid-state reaction and synthesized nanoparticles were subjected to different characterisations such as X-ray diffractometer (XRD), UV–Vis-Spectrophotometer (UV–Vis–NIR), field emission scanning electron microscopy (FE-SEM), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and I–V measurements. The X-ray diffraction patterns confirm the polycrystalline nature of the Cd_1-xAl_xO nanoparticles with cubic structure. From the XRD patterns, the crystallite size and other structural parameters were calculated. The diffuse reflectance spectra were used to calculate the optical bandgap of the Cd_1-xAl_xO nanoparticles and it increased with increase of aluminium (Al) concentration (2.00 eV–2.04 eV). The FT-IR spectra confirm the Cd–O vibrational bands in the Cd_1-xAl_xO nanoparticles.

The morphological studies revealed the spherical shape of the synthesized nanoparticles. The XPS spectra confirm the presence of aluminium (Al), cadmium (Cd) and oxygen (O) in the desired ratios. The current versus voltage characteristics of the Cd_1-xAl_xO nanoparticles were studied using Keysight source metre.

在本研究中，采用固态反应制备了浓度为（x = 0.00、0.03、0.05 和 0.07）的_{铝掺杂氧化镉 (Cd 1-x} Al _x O) 纳米粒子，并对合成的纳米粒子进行了不同的表征，例如 X射线衍射仪(XRD)、紫外可见分光光度计 (UV-Vis-NIR)、场发射扫描电子显微镜 (FE-SEM)、傅里叶变换红外光谱(FT-IR)、X 射线光电子能谱 (XPS) 和I-V 测量。X射线衍射图证实了具有立方结构的Cd _1-x Al _x O纳米粒子的多晶性质。根据 XRD 图案，可以计算微晶尺寸和其他结构参数。漫反射光谱用于计算Cd _1-x Al _x O纳米粒子的光学带隙，它随着铝（Al）浓度的增加而增加（2.00 eV-2.04 eV）。_{FT-IR 光谱证实了 Cd 1-x} Al _x O 纳米颗粒中的 Cd-O 振动带。

形态学研究揭示了合成纳米颗粒的球形形状。XPS 光谱证实存在所需比例的铝 (Al)、镉 (Cd) 和氧 (O)。使用是德源表研究了Cd _1-x Al _x O 纳米颗粒的电流与电压特性。
