A photoluminescent material comprising a composition of halogen-substituted alkaline earth metal aluminate doped with at least one rare-earth element activator. The alkaline earth metal is selected from one or more of Sr, Ca, Mg and Ba. The halogens can be F, Cl, Br and I. The invention includes a method of manufacturing the photoluminescent material and use of the photoluminescent material in long after-glow products such as water based and/or solvent based paints and extruded from plastics, ceramic glazes and the like. |
