Organic CdTe quantum dots with average size of about 4.5 nm were synthesized in organic solution using dodecanethiol as stabilizing reagent.Nanocomposites of CdTe/polymethyl methacrylate(PMMA) and CdTe/Eu/PMMA were prepared via the van der Waal force interaction or the ionic coordination respectively by mixing organic CdTe quantum dots or triisopropoxyeuropium and organic CdTe quantum dots with PMMA.The resultant nanocomposites were characterized by infrared spectra(IR),ultraviolet absorption spectra(UV-Vis),fluorescence spectroscopy(FS),scanning electron microscope(SEM) and transmission electron microscope(TEM).The results indicated that CdTe/PMMA emitted strong red light under UV-Vis excitation in solution or in film.However,the CdTe/Eu/PMMA also emitted red light,but with decreased relative intensity than that of CdTe/PMMA.The emission of europium and organic CdTe quantum dots in CdTe/Eu/PMMA quenched because of the interaction between the organic CdTe quantum dots and europium ion.
