Eu 2+ doped calcium aluminate coatings were prepared by the dip-and spin-coating methods on a-alumina substrates. This kind of persistent luminescent coatings may replace the luminous paints used in many applications. If sol-gel methods are used the expense of preparing the coatings is relatively lo
## Abstract Polycrystalline hexagonal alkaline earth aluminates M~3~Al~16~O~27~ doped by divalent europium were prepared by solid state reaction. The crystal structure and optical properties at room temperature were investigated. The structure parameters were refined using Rietveld refinement proce
