Multicolor solid state light emitting diode / laser |
| abstract |
(57) Abstract: A light emitting diode (LED) (10) grown on a substrate (16) doped with one or more rare earth elements or transition elements. The dopant ions absorb some or all of the light from the active layer (11) of the LED and excite the electrons of the dopant ions to a higher energy state. The electrons are naturally pulled back to their equilibrium state and emit light of a wavelength determined by the type of dopant ion. The present invention is particularly applicable to nitride-based LEDs (10) that emit ultraviolet light and are grown on chromium-doped sapphire substrates (16). Chromium ions absorb ultraviolet light and excite the ion's electrons to a higher energy state. The electrons emit red light when returning to their equilibrium state, and some of the red light emits from the surface of the LED. |
