Abstract: In this paper, we reported the variances of optical properties of CdSnanoparticulates in reverse micelle as the size and interfacial chemical condition were changed.TCNQ(7,7,8,8-tetracyanoquinodimethane) molecules on the surface of CdSnanoparticulates could induce the acceptor bound excitonic states, increasing the binding energy between electron and hole, which was in relation to the red-shift of optical absorption band edge and the well-discrete optical absorption and photoluminescence structures.This composite system would find applications in optical memory, optical nonlinearity, electron localization and so on.

Key words: CdS nanoparticulates, Optical properties, Bound excitonic states
