Abstract: A method of manufacturing a luminescent tile for use in an aqueous environment includes admixing a luminescent pigment capable of being illuminated by an external light source, a forming material, and a catalyst to create a luminescent mixture. Casting the luminescent mixture into a mold and allowing said mixture to substantially harden thereby creating a luminescent tile. The forming material permits luminescence from the luminescent pigment upon excitation by an external light source, such as, a blacklight, while allowing the luminescent pigment to be safely used in an aqueous environment, such as a pool, spa, or the like.

Abstract: An encapsulated photoluminescent particle. The photoluminescent particle may be used in the formation of aggregates. The aggregates may be used in the formation of various substrates, especially for aqueous environments, such as swimming pools, aquariums, spas and fish ponds. In general, the photoluminescent particles include a resin, a photoluminescent compound, and a catalyst. The composition may be granulated to form the photoluminescent particle. The photoluminescent particles may be formed without the need of additional filler materials.
