Preparation of PANI@ZnS Quantum Dots Composite Nanomaterials and Its Luminescent Properties

PANI@ZnS quantum dots composite materials were prepared by two steps.First,ZnS quantum dots were synthesized by hydrothermal method at a constant temperature of 150℃,and then PANI@ZnS composite quantum dots were obtained with the in situ polymerization of aniline.The products were characterized by X-ray diffractometer (XRD),ultraviolet-visible spectra (UV-vis),infrared spectra (IR),Raman spectra (Raman),transmission electron microscopy (TEM).The PL patterns show that the PANI@ZnS peaks are broaden compared to the ZnS peak and exist the clearly blue shift.
