Rezumat

An artificial block of concrete and sand was made, coated with a SrAl₂O₄:Eu²⁺, Dy³⁺-based phosphor, and a new direction in the study and application of persistent phosphors was proposed. For the first time underwater luminescence on the coral surface was experimentally studied in real sea conditions. A bright, long-lasting blue-green afterglow was registered from a depth of 5 m. Fishes were attracted to the light of this artificial reef.
