- Light-emitting diode - Wikipedia
Electroluminescence, from a solid state diode, was discovered, in 1906, by Henry Joseph Round, of Marconi Labs, and published, in February 1907, in Electrical World; Round observing various carborundum (silicon carbide) crystals would emit yellow, light green, orange or blue light, when a voltage was passed between the poles [9] A silicon carbide LED was created by Soviet inventor Oleg Losev
