title: Full-color illumination that needs no electric power.
abstract: Red, green, and blue phosphorescent resins were developed to realize full-color illuminators that shine without the need for electric power. Red phosphorescence, which used to be weak with conventional red phosphors, was enhanced notably with dye-doped resins in which green or blue phosphors were dispersed uniformly; i.e., brightness increased by seven times and afterglow duration extended by two times. Full-color phosphorescence from violet to red was attained by selecting suitable mixing ratios of the phosphors and dyes.
