Abstract: Single-phase SrAl$_2$O$_4$:Eu$^{2+}$ and multiphase {SrAl$_2$O$_4$+Sr$_4$Al$_{14}$O$_{25}$}:Eu$^{2+}$ phosphors, as well as those codoped additionally with Dy$^{3+}$, are prepared by solid state reaction and combustion synthesis. The codoping of SrAl$_2$O$_4$:Eu$^{2+}$ with Dy$^{3+}$ leads to an increase in the afterglow duration from a few minutes up to many hours and makes the afterglow much brighter, which is important in some applications. 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 are applied to control the synthesis process. The presence of different emission centers and their distribution in the studied phosphors is shown. Some of their numerous applications, such as display devices, painting, and biological applications, are shown.
