2012/2/21· Modern white LEDs are based on indium gallium nitride (InGaN), deposited on a transparent substrate such as sapphire or silicon carbide (SiC). The band gap of InGaN can be manipulated by altering the ratio of GaN to InN such that emitted photons are in the 390 to 440 nm part of the spectrum (ultraviolet, violet-blue, and blue).
