The group II-IV nanoparticles have excellent semiconducting properties having a possibility of tuning it by changing the size, shape and precursors. This makes them an ideal candidate for their applications in the field of science and technology. Amongst several semiconductor nanoparticles, zinc sulphide (ZnS) nanoparticles are promising material because of chemical stability, low toxicity and better optical properties. Introducing transition metal impurities in ZnS nanoparticles further improves the physical properties like optical and magnetic. The synthesis and optical properties of transition metal doped ZnS nanoparticles with varying doping percentage is reported. The doping of ZnS with the transition metal with variable doping concentration improves the luminescence in comparison of pure ZnS. The photoluminescence spectrum has a single major peak at 780nm, and the intensity increases with the type and concentration of the impurity but at higher concentration the luminescence is quenching. This paper tries to give a comprehensive study of photoluminescence of ZnS nanoparticles doped with different transition metal with varying concentration.
