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 Β°C. The influence of the thermal treatments on the stability, homogeneity and structure as well as to the UV-excited and persiste
