One of the persistent luminescence materials and providing emission in blue-green areas emission bands for typical phosphors (SrAl_2O_4:Eu^{2+}, CaAl_2O_4:Eu^{2+}, MgAl_2O_4:Eu^{2+}) are generally focused on recently. These systems are reliable, stable, not containing radiation and they have long term photoluminescence emission. These systems are mainly used in a wide range of products such as building, ceramics, line marks for highways, tolls, etc. In this study, SrAl_2O_4:Eu^{2+} phosphorescent pigment was used on wall tile surfaces. Due to the high firing temperature after-glow property of the pigment decreases. To increase afterglow property frit compositions with low temperature melting point were developed and depend on the composition, after-glow properties of the tiles were measured by photometer.
