Abstract—By changing the stabilizer system and synthesis temperature, ZnCdTe alloy have been controllably synthesized in aqueous solution using a simple route. A high synthesis temperature leads to nanoparticles growth using thioglycolic acid (TGA) as the stabilizer, whereas a low synthesis temperature promotes the form of nanorods using TGA and L-Cysteine（L-Cys）as the stabilizer. The different morphologies of samples have been characterized by transmission electron microscopy (TEM). The optical properties of the obtained ZnCdTe nanorods and nanoparticles have been investigated by photoluminescence (PL) spectroscopy with different refluxing times. We have also demonstrated electroluminescence (EL) property from heterostructure device fabricated with the prepolymer of Poly(p-phenylenevinylene) (PPV ) and ZnCdTe alloyed nanocrystals. Current density of device with ZnCdTe alloy in emitting layer is obviously increased.
