Cadmium Sulphide (CdS), a II-VI group binary compound is prepared in laboratory through chemical method. Quantum dot sizes are restricted with uniform size distribution and the synthesis is done along with poly vinyl Alcohol (PVA) Matrix. Absorption Spectroscopy in the UV range, XRD and HRTEM studies are carried ooutto characterise its nano properties : size and concentration. The second order non-linear effect expected to be produced by the sample leads to its application as Second Harmonic Generation. The sample depicted successfully in photoluminescence study. Also, in this paper an attempt has been made to justify the generation of second harmonic generation in our as-prepared CdS quantum dots.
