Polycrystalline Eu 2+ and Dy 3+ doped barium aluminate materials, BaAl 2 O 4 :Eu 2+ ,Dy 3+ , were prepared with solid state reactions at temperatures between 700 and 1500 ยฐC. The influence of the thermal treatments on the stability, homogeneity and structure as well as to the UV-excited and persiste
