Hope, I'll find a lot of answers here. Recently in the Internet I've found new powder that glows in the dark after being exposed to natural or artificial light. Have you ever heard about it? Did you use it? Any information is appreciated.
Luminophore is a fine-grained non-flammable powder, and does not contain any radioactive isotopes. The duration of the glow is up to 8 hours. The general principle is such: if the lacquer is "charged" for 5 hours, then it can be expected that afterglow will also be approximately 5 hours.
