A simple aqueous method was used to synthesize a blue-green emitting Ce3+ doped SrS nanocrystalline phosphor. SrCl2, Na2S2O3 and Ce(NO3)3 were used as precursors for Sr2+, S2- and Ce3+ ions respectively. Ethlylene diamine tetra acetic acid (EDTA) was used as a complexing agent. XRD studies revealed the single crystalline phase of the SrS:Ce3+. The morphology was examined using SEM and TEM and average particle size estimated from TEM images was 25 ± 2 nm in diameter. The elemental composition was analyzed with the electron dispersive x-ray spectroscopy (EDS). The photoluminescence (PL) study showed two emission peaks at 480 nm and 527 nm ascribed to the 2D(5d)→2F5/2(4f) and 2D(5d)→ 2F7/2(4f) transitions of the Ce3+ ion in SrS:Ce nanophosphors. These peaks are blue shifted from bulk SrS:Ce peaks at 485 nm and 530 nm. The intense emission peak at 480 nm at 254 nm excitation may be explored for possible applications in gamma and x-rays scintillators.
