Abstract

PROBLEM TO BE SOLVED: To provide a sheet which is serviceable at a site, such as a walking space or a car passage by enhancing the durability of a light emitting material which is excellent in wear resistance and weatherability and which is capable of emergency-guide walking and driving under the guide of light emitting aggregates at night or during a power failure. SOLUTION: This optical guidance sheet uses an inorganic ceramic emitter which contains a light emitting material which exerts a light emitting characteristic under the irradiation of light and which is crushed into a small-particle aggregate 3 and mixes the aggregate 3 with a small particle non-slip aggregate 4, such as a hard ceramic or a stone material so that it may be fixed with the surface of a plastic sheet or a cloth with a bonding agent with the upper end exposed where a guide passage or a mark displayed by the layout of the light emitting material 3 can be visually confirmed.

As a result, both the fluorescence emission property and the phosphorescence emission property were good. The fluorescence emission test was conducted by irradiating a car headlight from a place 10 m away at night and visually evaluating its luminescence.

It was not done. In addition, when a luminescent aggregate composed only of the phosphorescent phosphor is used, the fluorescent luminance at the time of irradiation is low, but the phosphorescent luminance after the light is turned off is high, and in a very dark place such as a country road, where there is no surrounding light such as a country road. It is valid. In this example, since the ultraviolet fluorescent material and the phosphorescent fluorescent material are used in combination, the fluorescent light emitting property and the phosphorescent light emitting property are excellent.
