Question
Light emitting diodes work by creating an electrical circuit where electrons fall across a “band gap" (i.e. they go from a high energy state to a low energy state). The larger the gap, the more energy they emit when they fall. This energy is emitted as a photon (i.e. a particle of light). The color of light generated by the LED is directly related to the size of the band gap. A large energy change results in blue light and small energy changes results in red light. Because LEDS made of pure elements can only emit light that is too high or too low in energy for us to see, mixtures of elements must be used to create a band gap that results in visible light. The table below summarizes the composition and properties of three different elemental combinations used in LEDS. Table 1: Composition and Properties of LEDS Element 1 Element 2 Size of Band Gap LED Color Gallium Nitrogen Large Blue Gallium Phosphorous Medium Green Gallium Arsenic Small Red
