Herein, structural and optical properties of Cu2MSnS4 (M = Co and Fe) nanoparticles synthesized by ultrasonic-assisted sol–gel method using two different solvents are studied. XRD study shows the nanoparticles with tetragonal kesterite structure and crystallite size in the range of 4–7 nm. XPS study reveals the oxidation state of constituent elements. The optical band gap and textural properties like surface area and pore size are estimated through UV–VIS–NIR and nitrogen adsorption–desorption analyses.

超声辅助溶胶-凝胶法合成Cu 2 MSnS 4的溶剂依赖性结构和光学性质

在此,研究了使用两种不同溶剂通过超声辅助溶胶凝胶法合成的Cu 2 MSnS 4(M = Co和Fe)纳米粒子的结构和光学性质。XRD研究表明,纳米颗粒具有四方硅藻土结构,微晶尺寸在4-7 nm之间。XPS研究揭示了组成元素的氧化态。通过UV-VIS-NIR和氮吸附-解吸分析可以估算出光学带隙和诸如表面积和孔径之类的纹理特性。
