Abstract—: Single phase SrAl2O4:Eu2+ and multiphase {SrAl2O4 + Sr4Al14O25}:Eu2+ phosphors were prepared by solid state reaction and combustion synthesis. It is shown that the emission band of the phosphors can be shifted from green to blue-green spectral range by changing the synthesis method. Composite color cathodoluminescence and photoluminescent analysis were applied to control the synthesis process. The presence of different emission centers and their distribution in studied phosphors was demonstrated.
