Abstract: Synthesis and characterization of undoped and Mn2+ doped ZnS nanocrystallites (radius 2-3 nm) embedded in a partially densified silica gel matrix are presented. Optical transmittance, photoluminescence (PL), ellipsometric and electron spin resonance measurements revealed manifestation of quantum size effect. PL spectra recorded at room temperature revealed broad blue emission signal centred at similar to420 nm and Mn2+ related yellow-orange band centred at similar to590 nm while ESR indicated that Mn in ZnS was present as dispersed impurity rather than Mn cluster.
