Özet

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 PH6. 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. © 2012 IEEE.
