A sharp luminescence peak from Sm doped ZnS at 650 nm which can be assigned as 4 G 5/2 -6 H 9/2 transition of Sm 3+ ion was observed; however, no luminescence peak related to Eu 3+ , which can have luminescence in the similar spectral region, was observed from Eu doped ZnS. A defect level situated a
Zinc sulfide semiconductor nanocrystals doped with selected transition metal ions (Mn 2+ , Cu 2+ , and Ni 2+ ) have been synthesized via a solution-based method utilizing low dopant concentrations (0-1%) and employing poly(vinylpyrrolidone) (PVP) as a capping agent. UV/Vis absorbance spectra for all
