Researchers light the way for organic glow-in-the-dark materials

摘要

By tweaking the emission mechanism and the molecules used,researchers improved the performance of organic glow-in-the-dark materials by tenfold.Glow-in-the-dark materials are utilized worldwide for emergency signs,watches,and paint.This useful characteristic fuels a global market worth approximately US$400 million.But the inorganic crystals that are currently needed to generate this ability to a high level of performance require rare-earth metals and fabrication temperatures of over 1000 degrees Celsius.Now,writing in Nature Materials https://go.nature.com/34oEYWD,researchers from the Okinawa Institute of Science and Technology Graduate University(OIST)and Kyushu University,both in Japan,have developed a method to generate a glow-in-the-dark light using the more-readily available organic materials.
