Abstract:The nanocomposite composed of CdSe quantum dots and conductive polymer (MDMO-PPV) was investigated. The spherical 3.8-nm functionalized CdSe quantum dots were synthesized by colloidal chemical method. The conductive polymer MDMO-PPV was synthesized from 1-methoxyl-4-(3,7dimethyl-octanoxyl)benzene and 4-Methoxylphenol. The quantum dots were mixed with MDMO-PPV before and after polymerization. It was found quantum dots will affect the polymerization of MDMO-PPV. The photoluminescence (PL) peaks from CdSe and MDMO-PPV was 595 nm (FWHM~25 nm) and 555 nm (FWHM~50 nm), respectively. Photoluminescence and optical absorption spectra of nanocomposite displayed mixed characters of quantum dots and MDMO-PPV.
