Summary, etc. ZnS nanoparticles embedded in polyvinyl alcohol (PVA) matrix have been synthesised with different <em>p</em>H by using wet chemical methods at room temperature. X-ray diffraction (XRD) pattern indicated that prepared nanoparticles with different <em>p</em>H show cubic phase. The average size variation of nanoparticles with <em>p</em>H estimated from the Debye-Scherrer equation and varying optical size by using absorption edge. Also, UV-Vis absorption results show a blue shift by variation of <em>p</em>H. The intensity of PL emission was found to be dependent on the <em>p</em>H of precursors and maximum of intensity related to <em>p</em>H=6. As a conclusion, <em>p</em>H plays vital role in improving PL intensity. It is also observed that particle size depends on the <em>p</em>H and a decrease in the size of particles is observed with the decrease of <em>p</em>H.
