realglow pigments in paint

Self-luminous fluorescent agents are mostly carried by its own trace of radioactive material realglow pigments in paint ray excited luminescence fluorescent agent . The storage agent is basically fluorescent light does not contain radioactive materials , but requires advance and reserve sufficient strength to absorb external light, the electrons from their high energy level to a lower energy level transitions and stored . When darkness surrounding environment , and then gradually slow release realglow decorative stone absorption of energy from the high energy level at this time electronic transitions to the low-level , fluorescent agents began to glow. Because of photoluminescent material itself does not carry ray excitation , so the degree of temporary inferior afterglow lasting self-luminous .
