SYNTHESIS OF CdSe CRYSTAL USING HOT INJECTION METHOD

CdSe semiconductor is highly luminescent crystals which are synthesized using hot injection method. The band gap of nano crystals are controlled by gradual incorporation of sulphur to CdSe nano crystals by applying asymmetric composition of reactants. The maximum emission wavelength of the grown nano crystals are varied by controlling the concentration ratio of VI group element Cd with Se in the reactant mixture. We use the colloidal hot injection method to synthesize CdSe quantum dots. The shape of resulting nano-crystals can be altered by changing time and temperature of the reaction.
