75 Years of Innovation: LED, first blue-light emitting diode
This process developed at RCA belies the complexity of the problem of emitting blue light. Commercial red-light emitting diodes were developed in the early 1960s. Red LEDs used gallium arsenide phosphide (GaAsP) as the substrate for the diode; yellow emitting diodes came soon after. But blue was a color that eluded LED science.

Gallium Arsenide
2.5.11 Properties of gallium arsenide nanoparticles. Gallium arsenide (GaAs), a group III–V compound, is the second most common semiconductor material after silicon. Unlike silicon, GaAs has a direct bandgap of 1.4–1.45 eV at bulk scale, which makes it more suitable than silicon for highly efficient light emission.
