ABSTRACT:
A full color display comprising a red, a green, and a blue light emitting diode, each light emitting diode including a light emitting region having at least one layer of single crystal rare earth material, the rare earth material in each of the light emitting diodes having at least one radiative transition, and the rare earth material producing a radiation wavelength of approximately 640 nm in the red light emitting diode, 540 nm in the green light emitting diode, and 460 nm in the blue light emitting diode. Generally, the color of each LED is determined by selecting a rare earth with a radiative transition producing a radiation wavelength at the selected color. In cases where the rare earth has more than one radiative transition, tuned mirrors can be used to select the desired color.
