Traditional fluorescent coating material can be divided into spontaneous and light-storing two. Light fluorescent agent is on their own on their own carry traces of radioactive substances emitted rays excite fluorescent fluorescence. Light-storing fluorescence Agent Basic does not contain radioactive substances, but require lightabsorption in advance and reserve sufficient strength to the outside world, its electronics by low level jump to the high energy level and store it. When the surrounding darkness, then slowly release the absorbed energy itself, and electronics from high energy tolow energy level transitions, fluorescent agent starts to glow. Because light-storing does not itself carry Ray-inspired material, andafterglow duration of temporary light-than spontaneous.
