Abstract

Non-toxic, environment-benign colloidal ZnCuInS Nanocrystals (ZCIS NCs) were synthesized and the temperature dependence of the photoluminescence (PL) energy, line width, and intensity for the ZCIS NCs with different reaction time were studied in the temperature range from 50 to 280 K. Generally, for typical ZCIS NCs ensemble, it has been constantly observed that the PL peaks energy decrease with the experimental temperature raising and the value of Eg(0) decrease with the increase of reaction time. Furthermore, the full width at half maximums (FWHM) of the PL spectra increased with the experimental temperature raising. It was found that the temperature dependence of the integrated PL intensity of ZCIS NCs decrease with the experimental temperature raising and the intensity decrease much with increasing reaction time.
