NASA developed a new light source from certain Strontium crystals to use in dark areas that are non toxic and no electricity needed. Just pre- exposure to light.





Other than that there is nothing that lasts more than a few days and being non toxic.





BUt if u dont care about toxicity, then there is Radium. Ebay does sell very small quantities of radioactive isotopes that u can then mix with dark paints...then will glow in some spots forever...but being in the same room with them can cause leukemia or other cancers.Glow in the dark paint and powder?
Are you trying to paint a room? You should try a hardware store or the home depot or lowes.
