Latest Patents

Richardson holds a patent for a "Method of forming an amorphous aluminum nitride emitter including a rare earth or transition metal element." This invention provides a variety of optimal luminescent emitter layers, luminescent devices, and methods of fabricating the same. One embodiment of this invention includes an alternating current thin film electroluminescent device that features an AC power source and an emitter layer positioned between a pair of electrode layers. One of these electrode layers is transparent to visible light of a selected wavelength. The AC power source is connected across the electrode layers, and the emitter layer comprises a non-conductive amorphous alloy made of aluminum nitride and an Er luminescent center. When activated, the AC power source creates an electric field between the electrode layers across the emitter layer, resulting in the emission of visible light of the selected wavelength.
