INORGANIC PHOSPHOR, INORGANIC PHOSPHOR PASTE AND METHOD FOR PRODUCING INORGANIC PHOSPHOR

摘要

PROBLEM TO BE SOLVED: To provide an inorganic phosphor having excellent dispersion stability, a small particle diameter and excellent emission characteristics, an inorganic phosphor paste and a method for producing the inorganic phosphor.;SOLUTION: The inorganic phosphor has 0.5-3.5 g/cm³ apparent density, 0.1-1.0 μm average particle diameter and an excitation wavelength at 140-400 nm. The inorganic phosphor is produced by a liquid-phase method or a spray pyrolysis method and has Ba element, Gd element, Al element and an activator. The inorganic phosphor paste comprises the phosphor.;COPYRIGHT: (C)2004,JPO
