    Abstract: A zinc oxide crystal growth substrate is disclosed. The zinc oxide crystal growth substrate includes a thin layer of single crystal zinc oxide deposited on an self supporting substrate surface by a chemical deposition process. The chemical deposition process is selected from RF sputtering, CVD (chemical vapor deposition), MOCVD (metal organic chemical vapor deposition), spin coating, electrophoresis, and hydrothermal growth processes. The self supporting substrate may be amorphous, polycrystalline, or crystalline. The thin layer of zinc oxide has a crystal lattice which permits the crystal growth of a crystal compatible with zinc oxide. The compatible crystal has a lattice parameter within about 5% of a corresponding lattice parameter of the zinc oxide.

    Abstract: Up-conversion and down-conversion photo-luminescence in rare earth compounds are disclosed. Broadband, super-radiant, and discrete line emissions are observed. The rare earth compounds include a rare earth element and at least one other element selected from chalcogens, halogens, nitrogen, and phosphorus. The rare earth compounds include, but are not limited to, rare earth oxides, fluorides, and oxyfluorides. Doping and co-doping of rare earth compounds in an optical host material is not required. The compounds are irradiated with incident light having an incident wavelength that is selected to be highly absorbed by the rare earth compound. The up-conversion and down-conversion luminescence have been observed which may be caused by unknown electron transitions, particularly in the case of ytterbia.

    Abstract: Electroluminescent materials and devices which emit non-thermal light in response to an electric field are disclosed. The electroluminescent materials are based upon a multicomponent ceramic oxide host compound and one or more metal oxide dopant compounds which form a solid solution with the ceramic oxide host compound. The dopant is present in the host at an amount in the range from about 0.002 mole % to 0.1 mole %. In the electroluminescent devices, a layer of electroluminescent material (12, 32) is disposed between a transparent conductive oxide layer (14, 34) and a ground plane (16, 36). An electric field generator (18, 38) is electrically connected to the conductive oxide layer (14, 34) and the ground plane (16, 36) for generating an electric field. The layer of electroluminescent material (12, 32) is coated with at least one barrier layer (20, 40), and preferably a pair of barrier layers, to inhibit chemical reaction of the electroluminescent material. The electroluminescent devices preferable include a dielectric layer (42).
