Structural, optical and electrical properties of spherical shaped wurtzite ZnS nanoparticles dispersed in polyvinyl alcohol matrix

Synthesis and characterization of biopolymer protected zinc sulphide nanoparticles

“…(8) I dark , I ph and S under 5 V applied biased voltage are found to be 1.0 Â 10 À8 A, 5.2 Â 10 À6 A and 5.19 Â 10 4 % respectively for the ZnS photo detector. Thus the photocurrent in the present study is approximately two orders of magnitude larger than that obtained in other relevant report [49]. The large photocurrent and photosensitivity can be ascribed to the presence of abundant carriers collected under illumination in the ZnS sample.…”
