Outline of Final Research Achievements

In order to promote the use of luminous fabric, the following contents were experimentally verified. 1) Effect of light sources found in daily life on phosphorescence intensity of luminous fabric. 2) Character identification using luminescence in dark environments. 3) Improvement of visibility and sustainability of luminous fabric by making the luminous cloth wavy. 4) luminous performance during times of poor visibility in preparation for disasters.
In order to obtain high luminance, light sources found in daily life that have a wavelength range that excites phosphorescent materials and have high irradiance are effective. By making the luminous cloth wavy, a certain degree of visibility was achieved even in poor visibility. On the other hand, the afterglow rate is not proportional to the luminance, and improving its persistence is a future research topic.

Academic Significance and Societal Importance of the Research Achievements

本研究で実験的に検証した蓄光布による文字識別の有効性や、立体形状による高視認性とりん光輝度の持続性の改善、視界不良時を想定した研究成果は、普段から着用している衣服やその他の繊維製品へ蓄光布の利用を促すことにつながり、予期せぬ災害に伴う停電や火災時の暗闇の中でも、ヒトやモノの存在が認識しやすくなる。普段からの蓄光布の活用によって、災害救助や避難の際に迅速な対応が可能となることから、人命を守るために社会的にも意義のある研究である。また、このような蓄光布の視認性や持続性は学術的に研究がほとんどされておらず、今後の研究発展が期待できる。
