Abstract :
ZnS nanoparticles embedded in polyvinyl alcohol (PVA) matrix have been synthesis with different PH by using wet chemical method at room temperature. UV-vis absorption result show a blue shift by variation of PH The intensity of PL emission was found to be depended on the PH of precursors and maximum of intensity related to PH=6. As conclusion, PH plays vital role in improving PL intensity. It is also observed that particles size depend on the PH and a decrease in the size of particles is observed with the decrease of PH.
