Radioluminescent paint is a self-luminous paint that consists of a small amount of a radioactive isotope (radionuclide) mixed with a radioluminescent phosphor chemical. The radioisotope continually decays, emitting radiation particles which strike molecules of the phosphor, exciting them to emit visible light.

PPG expanded quickly. By 1900, known as the "Glass Trust", it included 10 plants, had a 65 percent share of the U.S. plate glass market, and had become the nation's second largest producer of paint. [4] Today, known as PPG Industries, the company is a multibillion-dollar, Fortune 500 corporation with 150 manufacturing locations around the world.
Photoluminescence (abbreviated as PL) is light emission from any form of matter after the absorption of photons (electromagnetic radiation). [1] It is one of many forms of luminescence (light emission) and is initiated by photoexcitation (i.e. photons that excite electrons to a higher energy level in an atom), hence the prefix photo- . [ 2 ]
The workers had been told that the paint was harmless. [1] During World War I and World War II, the company produced luminous watches and gauges for the United States Army for use by soldiers. [2] U.S. Radium workers, especially women who painted the dials of watches and other instruments with luminous paint, suffered serious radioactive ...
Pratt & Lambert is a brand of architectural and industrial paint founded in 1849. It has been owned by Sherwin-Williams since 1995. The Pratt & Lambert company started in Buffalo, New York in 1849 as a maker of a drying agent for linseed oil paint. It was listed on the American Stock Exchange in 1905.
Electroluminescent displays found, for example, in aircraft instrument panels, use a phosphor layer to produce glare-free illumination or as numeric and graphic display devices. White LED lamps consist of a blue or ultra-violet emitter with a phosphor coating that emits at longer wavelengths, giving a full spectrum of visible light.
