ZnS nanoparticles, Maganese doped zinc sulfideAbstract
Nano-particles of without and with manganese doping zinc sulfide (ZnS:Mn2+) with PVA (polyvinyl alcohol) as stabilizer were synthesized by chemical precipitation method at room temperature. The structural and optical properties of the ZnS:Mn nano-particles were characterized by X-Ray diffraction (XRD), field emission scanning electron microscopy (FE- SEM), energy dispersive X-ray spectroscopy (EDX) and photoluminescene (PL). XRD analysis showed the formation of cubic ZnS:Mn2+ particles with an average size of 2.2 nm. The PL analysis revealed the variation of emission peaks from 436 nm to 600 nm with Mn2+ doping, which suggested the effective energy transfer from the host ZnS material to the dopant Mn2+ ion. The results indicated that ZnS:Mn2+ can be used in the printing ink of security documents and labels, light – emitting diodes (LEDs), and also in novel flexible photoluminescent display screen.
