Has optical properties. Specifically, the sulphide phosphor has a decay time of about 200 minutes, while the strontium aluminate has a decay time of about 20 minutes.
It has an afterglow time of about 00 minutes. Therefore, when it is used as the paving stone A1, it has an afterglow time of 8 hours or more after sunset. Therefore, it is possible to obtain the guide display paving stone A1 having a luminous property that can be visually recognized overnight without containing a radioactive substance.

According to the paving stone A1 for guiding display according to the first embodiment described above, since the phosphorescent phosphor is mixed in the synthetic resin layer 30 of the paving stone A1 for guiding display, it can be used in darkness at night or the like. Even if there is, the phosphorescent phosphor of the paving stone A1 emits light, so that it is possible to display a traveling route to a pedestrian or the like. At this time, since strontium aluminate is used as the phosphorescent phosphor instead of the conventional zinc sulfide phosphor, it can be used outdoors and can be used as a paving stone. In addition, since it has a long-lasting afterglow characteristic, it can be viewed all night even at night. Furthermore, by emitting light at night, an illumination effect can be obtained, and the atmosphere of the pavement can be improved.
