  • Phosphor particles
    Patent number: 11124701
    Abstract: Provided are phosphor particles comprising Mn-doped complex fluoride red phosphor particles and inorganic fine particles which are affixed to the surface of each red phosphor particle. The Mn-doped complex fluoride red phosphor-containing phosphor particles are suppressed in mutual adhesion and agglomeration, flow well during mixing with a silicone or epoxy resin, and have excellent humidity resistance.
    Type: Grant
    Filed: February 5, 2019
    Date of Patent: September 21, 2021
    Assignee: SHIN-ETSU CHEMICAL CO., LTD.
    Inventors: Masami Kaneyoshi, Kazuyuki Matsumura, Yoshiteru Sakatume

  • CONDUCTIVE PASTE, METHOD OF PREPARATION, AND SOLAR CELL ELECTRODE USING THE SAME
    Publication number: 20170051165
    Abstract: A conductive paste includes electrically conductive particles, a binder, an organic solvent, a glass powder, and a specific amount of inorganic oxide particles that are at least partially surface-coated with an organophosphorus compound and have a specific average particle size. Solar cell electrodes formed by firing the conductive paste have increased bond strength with a substrate.
