(a) Photographs of ZnS:Mn core NCs (1) and ZnS:Mn/ZnS core-shell NCs (2), after preparation in microemulsion upon 366 nm UV (left) and day light (right) illumination. (b) Excitation and PL spectra of ZnS:Mn and ZnS:Mn/ZnS NCs in microemulsion. Inset: PL intensity of ZnS:Mn/ZnS core-shell NCs at 580 nm and 430 nm versus molar ratio of ZnS/ZnS:Mn.
