ZnS:Mn2+ nanocrystals (NCs) with particle size from 1.9 nm to 3.2 nm are synthesized via chemical precipitation method with different [S2−]/[Zn2+] ratios. The size dependent decay for Mn emission exhibits a double exponential behavior. And two lifetime values, in millisecond time domain, can both be shortened with size increasing, which is attributed to enhanced interaction between host and Mn2+ impurity...
Undoped ZnS nanocrystals (NCs) with different precursor molar ratios of [S2−]/[Zn2+] are prepared by the chemical precipitation method. The structural and optical properties of the samples are characterized by the X-ray diffraction (XRD) spectra, photoluminescence (PL) spectra and PL decay spectra. The XRD analysis shows that the crystal quality of ZnS NCs becomes better and the grain size is larger...
