The different sizes in nanometer of CdS ultrafine particles (UFP) are prepared throughmicroemulsion method. Their spectra show that CdS UFP has a prominent quantum size effect.It is for the first time to find the well defined structures in CdS UFP emission and excitationspecma at room temperature. The emission of surface state is significantly reduced in CdSUFP modified by surfactant molecules, but that may enhance X~((3)) of CdS UFP.
