Enhancement in photoluminescence emission in the UV-visible region from chemically synthesized silver doped ZnS nanoparticles

Sarkar R., Kumbhakar P., Mitra A.K., NIT Durgapur India, IN

Nanoparticles of ZnS:Ag doped with Ag+ (0.5%) and capped with polyvinyl pyrolidone (PVP) have been synthesized by chemical co-precipitation method. The measured particle size is ~2.5 nm which has been obtained from the analyses of [...]

Synthesis and optical properties of L-cystine capped ZnS:Co nanoparticles

Kumbhakar P., Sarkar R., Mitra A.K., National Institute of Technology, Durgapur, IN

IV-VI nanocrystalline semiconductors are of great interest for its applications in light emitting devices, fluorescence biosensor, and solar cells [1-4]. Here, we have reported synthesis of cobalt doped ZnS (ZnS:Co) nanoparticles capped with L-cystine by [...]
