The ZnS:Mn2+ nanocrystal colloidal solution is prepared by the in situ surface modification co-precipitation method in the presence of 3-mercaptopropyl trimethoxysilane (MPS). The increase in the fractional photoluminescence (PL) intensity by the aging of this solution is represented as a first-order reaction. Judging from the small activation energy, we conclude that Mn2+ ions are exchanged with Zn2+ ions at the surface of ZnS nanocrystals during aging to increase the PL intensity.
