Abstract

Polymer dispersion method, a new approach to obtain Q-CdS nanoparticles, has been presented. Four kinds of monodisperse Q-CdS with different sizes were constructed by using water soluble polymer as dispersion agents and 2-mercaptoethanol or dodecyl mercaptan as surface modifier in polymer networks. UV-vis spectra and TEM were used to determine particle size and observe the size distribution, and fluorescence properties of Q-CdS with different sizes were studied. Obtained results indicated that different Q-CdS nanoparaticles with small size and narrow distribution were quickly prepared by polymer dispersion method, and these samples showed obvious quantum size effect on UV-vis and fluorescent spectra.

Key words: Q-CdS, polymer dispersion method, preparation, quantum size effect
