Silica-protected, thioglycerol-(TG-) capped, highly luminescent, ZnS:Mn nanoparticles were synthesized. The resultant nanoparticles show a clear enhancement of photoluminescence intensity as compared to TG-capped ZnS:Mn nanoparticles without silica coating. The PL intensity peaks around 600 nm indicate that PL stems from embedded Mn ions after the irradiation is transferred from the excited ZnS to the Mn atoms. The silica shells did not modify the photoluminescence excitation or emission spectra except for changing the intensities. The silica shell was found to be semitransparent to UV and visible radiation.
