Composition dependent room temperature ferromagnetism and PL intensity of cobalt doped ZnS nanoparticles

•PVP capped ZnS:Co nanoparticles were synthesized at 80°C through chemical route.•Structural, band gap, PL and magnetization studies were carried out.•Doped samples exhibited concentration dependent room temperature ferromagnetism.•Appreciable enhancement in PL intensity was noticed in all the doped...
