Cu-In-Zn-S(CIZS) quaternary quantum dots (QDs) were prepared via a facile one-step method in aqueous solution. The effects of reaction temperature, cationic concentration and pH value of precursor solution on the phase composition, microscopic morphology and photoluminescence (PL) property were investigated by X-ray diffraction, transmission electron microscopy and fluorescence spectrophotometry. The results show that the crystallinity of QDs can be improved as the reaction temperature is increased, resulting in the increase of PL intensity. The PL intensity of CIZS QDs becomes the maximum value at 95 ℃. The particle size of CIZS QDs gradually decreases with the increase of cationic concentration, causing a blue shift of PL peaks from 634 nm to 617 nm. The optimized cationic concentration of precursor is 1.5 mmol/L. Moreover, the surface defects are effectively passivated by ligands at pH value of 5.0, resulting in the intense emission intensity. Based on the results by Fourier transform infrared spectroscopy, there are lots of functional groups on the surface of QDs, having a superior water solubility of QDs. The CIZS QDs have a promising application prospect in bio-imaging field.
