Synthesis and characterization of Cr doped CdS nanoparticles stabilized with polyvinylpyrrolidone

► Cr doped CdS nanoparticles were synthesized by chemical co-precipitation method using PVP as surfactant. ► The influence of Cr content on the physical properties of Cr doped CdS nanoparticles were investigated. ► The synthetic route could be adopted for producing high-quality gram scale synthesis of doped semiconductor nanoparticles.
