Eco-materials (environmental Materials) The development of Eco-materials (environmental Materials) that does not take the burden of the environment when the material itself is used or the material is useful for improving the environment will not be an exaggeration to say that Japan is leading the WORLD.
This is what I introduce this time. -n Luminous (Luminova) Conventional luminescent pigments, There are two types of "spontaneous light" and "phosphorescent". The former can be emitted overnight by radiation, but because the radioactive material is included, there is a restriction on the application, and it is necessary to manage it severely in production and disposal. On the other hand, the latter does not contain radioactive material, long-time emission was not difficult and practical. The n emission that is now attracting attention is not required radioactive material, yet it has been able to light up for a long time. The alumina compound was successfully commercialized in a special process of adding calcination of rare earth elements to the main component. The characteristic of this n-luminescence is the long-luminous ② residual light in ① darkness, luminance is a conventional 10-fold ③ light is strong enough to glow ④ resistance to outdoor use is also possible ⑤ chemical stability is high ⑥ light is low, such as the load on the ⑦ people and the environment to reach far. The development of applications for daily necessities, watches, automobiles and outdoor goods is progressing. Fundamental special chemistry is the first commercialized in the world, accounting for 80% of the world market Share.
