A novel red SrMoO 4 :Sm 3+ ,R + (R + = Li + , Na + , K + ) phosphor was prepared by solid state reaction method. XRD results showed that 950 °C was a suitable sintered temperature for preparation of SrMoO 4 :Sm 3+ phosphors. The emission spectra of the SrMoO 4 :Sm 3+ phosphors consisted of some sharp emission...
Eu 2+ and Dy 3+ co-activated CaAl 2 Si 2 O 8 -based long afterglow phosphor was firstly synthesized by solid state reaction. The phosphor emits a visible blue light under UV excitation and the blue afterglow lasts about 1 h in the dark. The phase-forming process of the phosphor was studied by means of differential thermal analysis (DTA) and X-ray diffraction...
