Chemical bath deposition method was used to create zinc sulfide (ZnS) nanoparticles. The CBD contained fixed components such as ZnCl 2 , NH 4 NO 3 and CS (NH ) KOH. Samples were heated at 90°C in a with magnetic agitation. Homogeneity, high transparency, adhesion, crystalline ZnS films achieved using KOH (1.4 M). For structural optical investigation, the produced nanoparticles are examined X-ra...
