Cadmium telluride (CdTe) nanocrystals were solvothermally synthesized using Cd(NO 3 ) 2 -4H 2 O and Te powder in ethylenediamine (C 2 H 4 (NH 2 ) 2 ) at 200 ° C for 12-72 h. Phase, morphology and photoluminescence (PL) property of the products were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and photoluminescence spectroscopy. The product synthesized at 200 ° C for 72 h was specified as cubic CdTe nanocrystals (41.39 nm) evaluated by the Scherrer equation, with 550 nm emission peak excited by 300 nm wavelength.
