Nanoparticles Of Copper, Zinc, Tin, And Selenide: Synthesis, Characterization and Applications

Abstract

Nanoparticles of copper, zinc, tin, and, selenide were synthesized by a method of preparation using salts of metal and selenium. Surfactant or capping agents were used to control the morphology. In CZTSe nanoparticles composition mainly depends on metal salts used for synthesis. Depending on solvents, different morphologies, and desired chemical composition. The use of nanoparticles incredibly increased in day-to-day life. Synthesis of CZTSe nanoparticles was done my using different methods. The bottom-up approach mainly used for synthesis of nanoparticles. Synthesized nanoparticles by colloidal method are easily dispersible in non-polar solvents. By using surfactants morphology was also controlled. The nanoparticles have large surface area because of their small size. The as-synthesized materials are identified with help of characterization techniques like, TEM, FESEM and SAED techniques. [1] Structural properties are easily informed my XRD. Optical characterization was used to know about the bandgap of particles. CZTSe are semiconductors and play important role in photovoltaic applications. [2]
