Novel inorganic luminescent materials have provided improvements in lighting, display, and optical devices. They are generally used for decorative applications, safety signs, and tolls. The characteristics of the photoluminescent pigments depend on both physical and chemical characteristics. In this study, particle size distribution effects on the after-glow time of the bluish-green and yellowish-green pigments were investigated. Milling times of the pigments were chosen as 30 min, 60 min and 90 min and they were applied on the wall tile surfaces with a constant ratio. Depending on the milling time, after-glow property of the pigments were compared by using photometer equipment. Correlations between pigments particle size distribution and after-glow time of the pigments were also discussed in this presentation.
