Light storage material is a kind of material that can store its light energy when irradiated by visible light, ultraviolet light and other light sources, and then slowly release the stored light energy in the dark state after the light source is evacuated to produce fluorescence phenomenon.
Optical storage materials can be widely used in military, navigation, fire protection, transportation and other fields. For example, in the event of sudden disasters such as earthquakes and fires at night, there are often power outages or emergency lighting facilities, and people need clear night vision guidance to escape smoothly in the dark. In theaters, schools, hospitals, residential corridors and other public places, light storage materials can guide people to enter and exit safely when lights are suddenly turned off or power is cut off at night. Night vision indicator lights are needed in highways, overpasses, underground passages and other places.
Ceramic materials have the characteristics of high strength, good weather resistance, heat and fire resistance, aging resistance, easy surface cleaning, elegant decoration and long service life. Light storage ceramic is a new type of functional ceramic which combines the advantages of light storage material and ceramic material.
Various wall and floor tiles made by adding light storage materials into ceramic glaze are called light storage ceramic tiles.
In addition to the above characteristics, light storage tiles can also be used in places with intermittent light sources, or artificially irradiated with intermittent light, which can produce continuous lighting effects, not only decorative effects, but also greatly save electricity. Therefore, some people call light-storing tiles "energy-saving building materials".
At present, the light storage performance of light storage tiles is: light receiving time 1~3min, light emitting time 2~ 12h.
At present, there is no corresponding national or industrial standard for light storage ceramic tiles, and the supply and demand sides should make specific agreements when selecting them.
