Phosphorescent pigments emit the absorbed light of a specific wavelength, when the light source is removed. It has been known for rather a long time that ZnS:Cu may emit green light, however, the glow it offers in applications where it is used and the continuity of such glow is limited (only a few hours). To eliminate this disadvantage, pigments with blue, green, bluish-green and yellowish-green radiation have been developed in the strontium aluminate system. Phosphorescence is derived in the dark when produced materials are held in sunlight or under ultraviolet light typically at 365-520 nm wavelength range. In this study, bluish-green and yellowish-green pigments were produced with phosphorescence property absorbing light of a specific wavelength (visible range) and emitting it in the dark with long glow time; afterwards it was sought to derive decorative or functional new ceramic products by using them in 3rd firing (decor firing) wall tile vetrosa applications and industrial tests were performed.
