The cоlоr оf the light emitted by semiconductor LEDs depends upon the bаndgаp of the pаrticular semiconductor. Three binary semiconductors that emit in the visible region are zinc sulfide (ZnS), zinc selenide (ZnSe) and zinc telluride (ZnTe). The color of the emission for semiconductor materials is determined by the size of the band gap, which in turn depends on several possible factors, e,g. electronegativity and atom size. Which one of these semiconductor materials would be expected to emit the shortest wavelength light in an LED?
