Luminova is a luminous paint developed by the Japanese company Nemoto & Co. Ltd. that, unlike older fluorescent colors, contains no radioactive substances.

The product Superluminova manufactured by the Swiss company Tritec (Super-LumiNova) is offering a further development of Luminova and a higher luminosity. Super-LumiNova is stimulated to shine by sunlight or artificial light, and the afterglow lasts up to 10 hours. This material has no limited lifetime, because the process of stimulating and afterglow happens without chemical reactions.
