JFK Boards | 60 Years OnMon. Oct 17, 2022Today's links from JFK Boards are here:Oswald's Rifle | Gen. Edwin WalkerErasing the Past..Secret Service interview with Marina Oswald re-Richard Nagell LED: Light Emitting DiodeSixty Years On | Oct. 17, 1962 (click here for video)
"Nick Holonyak, Jr., and S. F. Bevacqua, both engineers with the General Electric Company, announced their discovery of the physical process that would make the light emitting diode— the LED — practical, by submitting their paper "Coherent (Visible) Light Emission from Ga(As1−xPx) Junctions" to the weekly journal Applied Physics Letters, which would publish the work in its December 1 issue.
Although silicon diodes had been able to generate light on the infrared spectrum, it took a specific alloy of gallium (Ga), arsenic (As) and phosphorus (P) to generate visible light; initially, LEDs were limited to red light, but the GaAsP system would later be perfected with nitrates to produce other primary colors, making it possible to generate the full spectrum."
