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 t...
