Here, a green emission persistent luminescent phosphor LaSrAl3O7:Eu2+ which is chargeable by UV light, was synthesized by solid‐state reaction method. Elemental mapping and fluorescence microscopy photoluminescence of the sample demonstrated the homogeneous distribution of La, Sr, Al, O, and Eu in the phosphor. Rietveld refinement shows that the as‐prepared sample belongs to the tetragonal crystalline...
High‐saturated red phosphors Mn4+‐doped SrAl12O19 were prepared by solid‐state reaction methods. The luminescent properties of SrAl12O19:Mn4+ were systematically investigated. The excitation spectra indicated that SrAl12O19:Mn4+ could be effectively excited by both NUV light and the blue light of LED chips. The emission spectra exhibit two sharp peaks in the deep‐red region. The effects of codoping...
