Did You know?
Although, the first visible-spectrum (red) LED was developed in 1962 by Nick Holonyak, Jr., who was recognized as the inventor of LEDs, related work had appeared much earlier. Electroluminescence as a phenomenon was discovered in 1907 by the British experimenter H. J. Round at Marconi Labs. He passed current through a crystal of silicon carbide and a cat's-whisker detector, and noticed the gave-off light. This is the first known report of the effect of the light-emitting diode. In 1927, Russian inventor Oleg Losev reported creation of the first LED. His research was distributed in Soviet, German and British scientific journals, but no practical use was made of the discovery for several decades. Kurt Lehovec, Carl Accardo and Edward Jamgochian, explained these first light-emitting diodes in 1951 using an apparatus employing SiC crystals with a current source of battery.
