The blue-emitting phosphor SrGa
:Ce was prepared
whose crystallinity was analysed by X-ray diffraction. The excitation and emission spectra of SrGa
:Ce were measured and investigated
and the effects of the cerium concentration on the PL properties of SrGa
:Ce powder wrer studied. The results of PL measurement showed that SrGa
:Ce phosphor achieved an even more saturated blue emission
and the optimum cerium concentration for high efficiency and more saturated blue emission was ranged from 3.0 to 4.0 mol%.
