Abstract

CdS quantum dots have been synthesized from the precursors CdCl₂ and Na₂S via micro emulsion method at room temperature. Cetylpyridinium chloride (CPC) and 1-pentanol were used as emulsifying agents in water in hexane solution. The crystalline phase, surface morphology and optical properties have been studied through PXRD, HRSEM, UV-Vis and Photoluminescence (PL) spectroscopy. From the study the size of the nanocrystal was found as 2.5 nm.
