| This paper reviews the synthesis process of water-soluble CdTe quantum dots using mercaptopropionic acid. The state-of-art synthesis of CdTe nanocrystals was carried out under special conditions, and quantum dots with varying sizes were successfully produced. The optical properties were investigated in the synthesis process. The effect of electromodulation on the CdTe nanoparticles was also researched to optimize electro-optical properties with spectroscopic techniques under high voltage. The results clearly showed that as the heat treatment time increases, the absorption wavelength of the CdTe nanoparticles increases, and the applied voltage causes the band gap of all nanoparticles to decrease. |
