“…There are several reports on the synthesis of Cu 3 BiS 3 nanoparticles via colloidal ,, or solvothermal approaches, , and preparation routes for Cu 3 BiS 3 thin films have been reviewed by Deshmukh and Kheraj . Cu 3 BiS 3 films have been prepared via (reactive) sputter deposition, , chemical bath deposition, ,− electrodeposition followed by sulfurization, , or coevaporation. , Reports on solution-based thin film deposition approaches beyond chemical bath deposition are quite limited. So far, spray pyrolysis and coating of nanoparticle inks have been used for thin film preparation, and precursor routes based on copper and bismuth salts and sulfur sources such as thiourea , or based on CuO and Bi 2 S 3 in thiol–amine solvents mixtures have been investigated …”
