EFFECT OF Sn2+DOPING ON OPTICAL PROPERTIES OF THIOUREA CAPPED ZnS NANOPARTICLES

摘要

Here we are reporting the synthesis of Zn1–xSnxS (x = 0, 0.1, 0.2, 0.3) nanoparticles and their photoluminescence properties. Zn1–xSnxS nanoparticles were synthesized by using thiourea as a capping agent. All the samples were characterized by X-ray diffraction technique. XRD patterns show the particle size in the range 12-24.5 nm. It was found that, the addition of Sn2+ions causes the change in UV and PL spectra of ZnS nanoparticles. A broad and intense emission peak occurs at 460 nm for Zn0.8Sn0.2S nanoparticles
