A simple aqueous method was used to synthesize a blue-green emitting Ce 3+ doped SrS nanocrystalline phosphor. SrCl 2 , Na 2 S 2 O 3 and Ce(NO 3 ) 3 were used as precursors for Sr 2+ , S 2− and Ce 3+ ions respectively. Ethlylene diamine tetra acetic acid (EDTA) was used as a complexing agent. XRD studies revealed the single crystalline phase of the SrS:Ce 3+ . The morphology was examined using SEM and TEM and average particle size estimated from TEM images was 25±2nm in diameter. The elemental composition was analyzed with the electron dispersive x-ray spectroscopy (EDS). The photoluminescence (PL) study showed two emission peaks at 480nm and 527nm ascribed to the 2 D(5d)→ 2 F 5/2 (4f) and 2 D(5d)→ 2 F 7/2 (4f) transitions of the Ce 3+ ion in SrS:Ce nanophosphors. These peaks are blue shifted from bulk SrS:Ce peaks at 485nm and 530nm. The intense emission peak at 480nm at 254nm excitation may be explored for possible applications in gamma and x-rays scintillators.
