This article discusses the scientific and theoretical foundations as well as the practical significance of developing long-persistent luminescent innovative coatings based on SrAl₂O₄:Eu²⁺,Dy³⁺ nanophosphors. The luminescent properties of the strontium aluminate matrix and the roles of Eu²⁺ activator and Dy³⁺ co-activator ions in energy storage and persistent phosphorescence generation are analyzed. The synthesis methods, morphological and optical characteristics of the nanophosphors, and their incorporation into polymer-based composite coatings are examined. Furthermore, the light emission intensity, persistence duration, environmental resistance, and energy efficiency of the developed coatings are evaluated. The obtained results demonstrate that coatings based on SrAl₂O₄:Eu²⁺,Dy³⁺ nanophosphors have significant potential for applications in emergency lighting systems, construction materials, transportation infrastructure, safety markings, and decorative design.
