| Abstract: | Taking thiourea as stabilizer, CdSe quantum dots was directly synthesized in aqueous phase. Temperature and reaction time during preparation of precursor were investigated as well as solution pH, stabilizers type, stabilizer dosage etc. in synthesis of CdSe quantum dots. At last, the best preparation scheme was obtained. The water-soluble quantum dots prepared with the scheme has good fluorescence intensity, at the same time the scheme has high utilization rate of raw material, good environmental affinity, helpful for application of biological detection. |
