Glow-in-the-dark materials that shine with the whole range of visible colors, and can even produce white light, have been developed by Japanese researchers.
Phosphorescent materials absorb energy when exposed to light and emit that energy as light again over long time periods.
For some time scientist have known how to produce blue and green phosphorescent compounds that would last for hours however producing red that last more than just a few minutes eluded them. Until now that is. The team from Ryukoku University, Kyoto solved the mystery by adding red dye to green and blue phosphors.
