  • Patent number: 9340727
    Abstract: A method for producing film-coated alkaline-earth metal silicate phosphor particles that can have improved light-emitting characteristics may include a coating film having high moisture resistance. Strontium-containing alkaline-earth metal silicate phosphor particles are pretreated with an alkaline-earth metal compound solution whose strontium compound concentration is 1 to 15% by mass with respect to the phosphor particles and whose pH is 6 or higher but 10 or lower. Then, a base layer of an aluminum organic metal compound is formed on the surface of the pretreated phosphor particles. Then, the phosphor particles are coated with a coating material composed of a partially-hydrolyzed condensate of a silane organic metal compound, and are then dried and heat-treated to form, on their surface, a coating film made of an amorphous inorganic compound mainly containing Si and O.

Moreover, a light-emitting element is formed by such a film-formation method, and a high-definition light-emitting device can be manufactured. Through a film-formation substrate in which a reflective layer, a light-absorbing layer and a material layer are formed, the light-absorbing layer is irradiated with light, so that a material contained in the material layer is deposited on a deposition substrate which is disposed to face the film-formation substrate. Since the reflective layer is selectively formed, a film to be deposited on the deposition substrate can be selectively formed with a minute pattern reflecting the pattern of the reflective layer. A wet process can be employed for formation of the material layer.

  • Patent number: 7964235
    Abstract: The present invention is a ceramic discharge vessel for use in high-intensity-discharge (HID) lamps. The discharge vessel has a ceramic body and at least one seal region comprised of an aluminum oxynitride material. The seal region further has a surface layer for contacting a frit material wherein the surface layer is less reactive than the aluminum oxynitride material with respect to the molten frit during sealing. Preferably, the surface layer has a lower nitrogen content than the aluminum oxynitride material. The less reactive surface acts to minimize the formation of bubbles in the sealing frit during the sealing operation.

  • Patent number: 7943205
    Abstract: A composite article comprises a substrate having at least a substrate surface and a graded-composition coating disposed on a substrate surface. The composition of the coating material varies substantially continuously across its thickness. The coating reduces the transmission rates of oxygen, water vapor, and other chemical species through the substrate such that the composite article can be used effectively as a diffusion barrier to protect chemically sensitive devices or materials. An organic light-emitting device incorporates such a composite article to provide an extended life thereto.

  • Publication number: 20100316791
    Abstract: A supercritical vapor deposition method includes the following steps. Firstly, a fluid is provided. Then, the pressure of the fluid is increased to a supercritical phase such that the fluid becomes a supercritical solvent. Then, a coating substance is dissolved in the supercritical solvent, thereby preparing a solubility equilibrium supercritical solution. Then, a substrate is provided on a heating base, which is immersed in the solubility equilibrium supercritical solution. Afterwards, the heating base is heated to have the solubility equilibrium supercritical solution generate a precipitation driving force, so that the coating substance is precipitated out and deposited on the substrate as a film.

  • Publication number: 20100314558
    Abstract: A luminescent system includes a layer of donor material, an acceptor material and a barrier layer therebetween. The energy transfer between the donor and acceptor is biased to the acceptor layer, by an asymmetric energy transfer efficiency created by the barrier layer. Energy from the donor material is converted into photo-luminescence in the acceptor layer by discouraging photo-luminescence quenching caused by energy backflow.
