摘要：

The precursor bis-(morpholinodithioato-s,s')-Cd-Zn was prepared and the thin films of ZnxCd1 - xS deposited on sodalime glass substrate. A direct optical energy gap of 2.63 eV was obtained from the analysis of the absorption spectrum. The photoluminescence spectrum shows shift in the energy of the primary emission peaks as a function of the excitation energy. The shift was explained as due to the quantum size effect in nanometer thick polycrystalline films. Energy Dispersive X-ray Florescence (EDXRF) confirms the elemental composition of both the precursor and the films. (C) 1998 Elsevier Science B.V. All rights reserved.
