ZnSe quantum dots(QDs) with size of 3.75 nm were prepared in aqueous solution,and the poly [(2-wethoxyl-s-octyloxyl) phenylenevinylene](MO-PPV/ZnSe) QD composite material was obtained by transferring ZnSe Q dots to MO-PPV using the surfactant.The obvious enhancement of the luminous intensity and blue shift of the emissive peak are observed with the increase of the doping concentration of ZnSe QDs by studying the absorption spectra(ABS) and photoluminescence(PL) spectra of MO-PPV and ZnSe QDs.The blue shift of the emissive peak is nearly 10 nm under the quality ratio of 1∶0.181 between ZnSe and MO-PPV.The results show that there is energy transfer between MO-PPV and ZnSe QDs,which is the important reason for MO-PPV/ZnSe QDs composite material with the photoluminescence enhancement.
