    Abstract: Embodiments of the invention are directed to quantum dot light emitting diodes (QD-LEDs) where the electron injection and transport layer comprises inorganic nanoparticles (I-NPs). The use of I-NPs results in an improved QD-LED over those having a conventional organic based electron injection and transport layer and does not require chemical reaction to form the inorganic layer. In one embodiment of the invention the hole injection and transport layer can be metal oxide nanoparticles (MO-NPs) which allows the entire device to have the stability of an all inorganic system and permit formation of the QD-LED by a series of relatively inexpensive steps involving deposition of suspensions of nanoparticles and removing the suspending vehicle.

    Abstract: The present invention provides new and useful methods for preparing rare-earth oxysulfide phosphors. Advantageously, in accordance with the methods of the subject invention, rare-earth oxysulfide phosphors can be prepared with lower reaction temperatures and fewer processing steps than methods currently in use. In a preferred embodiment, the process of the subject invention involves blending two different rare-earth nitrate salts and a sulfidizing agent. Then, the mixture is heated at relatively low temperatures until the rare-earth oxysulfide phosphor is produced.

    Abstract: The subject invention pertains to a method, apparatus, and composition of matter for producing near-infrared (near-IR) radiation. The subject invention can incorporate a polymer and a metal-containing compound, wherein the metal-containing compound can incorporate a metal-ligand complex, wherein when the metal-ligand complex becomes excited, energy is transferred from the ligand to the metal, wherein, the energy transferred to the metal by sensitization is emitted as near-infrared radiation. In a specific embodiment, the subject invention relates to a composition of matter having a luminescent polymer and a metal containing compound where the metal containing compound incorporates a metal-ligand complex such that the absorption spectrum of the metal-ligand complex at least partially overlaps with the emission spectrum of the luminescent polymer. As the absorption spectrum of the metal-ligand complex at least partially overlaps with the emission spectrum of the luminescent polymer, when the luminescent polymer becomes electronically excited energy can be transferred from the luminescent polymer to the metal-ligand complex. At least a portion of the energy transferred from the luminescent polymer to the metal-ligand complex can then be emitted by the metal-ligand complex as near-infrared radiation. The subject invention can incorporate polymers which are conjugated or non-conjugated and luminescent or non-luminescent. In a specific embodiment, conjugated polymers which are luminescent can be utilized.

    Abstract: The luminance of a phosphor suitable for an alternating current thin-film electroluminescent device is substantially improved according to the present invention by including an alkali halide. The alkali halide included within the bulk of the phosphor material results in providing a significant number of trapping states which trap free electrons within the phosphor material. The addition of the trapping states (added defects) within the bulk tend to control the electrical and optical characteristics of the phosphor material. This reduces asymmetric light output characteristics of traditional phosphor material, reduces asymmetric current movement within the phosphor material, and decreases the influence of the interfaces between the phosphor material and insulating materials resulting in decreased aging and increased brightness.
