Introduction The phosphor systems, which can radiate long afterglow, are classified as energy-storing materials that can absorb the visible light and UV beams, store the photon energy and release the energy as visible light slowly.
Conclusions Long afterglow pigment Sr4Al14O25:Eu,Dy was synthesized by a solid-state reaction method with appropriate starting materials.
