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

## Abstract Nanocrystalline samples of Zn~1โx~Mn~x~S (x = 0.0, 0.02, 0.04) were synthesized by chemical precipitation method and characterized for magnetism. EPR studies showed an evidence of ferromagnetism around room temperature. Hysterisis from vibrating sample magnetometer supports the observat
Pb 2+ is synthesised via a precipitation method. The influence of the particle size on the luminescence of nanocrystalline ZnS : Pb 2+ is studied. Depending on the excitation wavelength, nanocrystalline ZnS : Pb 2+ shows a very broad white (l exc = 380 nm) or red emission (l exc = 480 nm). The red a
