Research Team Develops UV LEDs

An international research team has developed a method that enables them to create glass-based, inorganic light-emitting diodes (LEDs) that produce ultraviolet light. Scientists from Los Alamos National Laboratory and Italy’s University of Milano-Bicocca have developed a fabrication process using a wet-chemistry method to make a new, glass-based material capable of emitting UV light that can also be integrated with silicon chips. The glass is reportedly embedded with tin dioxide nanocrystals that are coated with tin monoxide, which act as semiconductor junctions. The shell’s thickness is used to control the material’s electrical response. They say this material could eventually be used to make biomedical devices with active components that are made from nanostructured systems. The full results have been published in Nature Communications. (EurekAlert)(Los Alamos National Laboratory)(Nature Communications)
