摘要

利用微波辅助溶剂热技术在不同Mn浓度(0,1%,3%和5%)下制备了锰掺杂的硫化镉半导体纳米粒子(CdS: Mn) NPs。用于制备mn掺杂CdS纳米粒子的化学物质是硫化钠(Na2S.xH2O)、氯化锰(MnCl2.4H2O)和醋酸镉(CH3COO)2Cd。、水)。为了确定纳米颗粒的结构尺寸,采用Debye-Scherer方程计算了衍射峰全宽半最大值(FWHM)处的平均晶粒尺寸。FTIR光谱分析用于观察mn掺杂CdS纳米颗粒样品中存在的各种功能和振动基团。用x射线衍射图检测了所制备纳米颗粒的结构特征。利用能量色散x射线确定合成纳米粒子的化学成分。利用紫外-紫外光谱对纳米粒子的光学性质和能带隙进行了定量分析。根据XRD计算,生成的纳米粒子的立方锌共混结构的晶体尺寸在4 ~ 7 nm之间。通过EDX光谱分析,证实了锰在CdS晶格处的掺入。

Study of structural, morphological and optical properties of Mn+2 doped CdS nanoparticles synthesized at various doping concentration
Manganese-doped cadmium sulphide semiconductor nanoparticles (CdS: Mn) NPs have been created utilizing a microwave-assisted solvothermal technique at different Mn concentrations (0, 1%, 3%, and 5%). The chemicals utilized for the preparation of Mndoped CdS nanoparticles were sodium sulphide (Na2S.xH2O), manganese chloride (MnCl2.4H2O), and cadmium acetate (CH3COO)2Cd., H2O). To determine the structural dimensions of the generated nanoparticles, the Debye-Scherer equation was used to calculate the average crystallite size at the full-width half maximum (FWHM) of the diffraction peaks. FTIR spectra analysis was used to look at the various functional and vibrational groups present in the Mn-doped CdS nanoparticle sample. The structure features of the produced nanoparticles have been examined using X-ray diffraction patterns. Energy dispersive X-rays were employed to ascertain the chemical composition of the synthesized nanoparticles. The optical properties and quantification of the energy band gap of the nanoparticles have been done using UV-V spectroscopy. According to XRD calculations, the cubic zinc-blend structure of the generated NPs had a crystal size of between 4 and 7 nm. By using EDX spectroscopy, the incorporation of Mn at the CdS lattice was confirmed.
