Title:
PHOSPHOR COMPOSITION, PHOSPHOR SHEET, PHOSPHOR SHEET LAMINATE, LED CHIP AND LED PACKAGE EACH USING SAID PHOSPHOR COMPOSITION, PHOSPHOR SHEET OR PHOSPHOR SHEET LAMINATE, AND METHOD FOR MANUFACTURING LED PACKAGE
Document Type and Number:
WIPO Patent Application WO/2015/060289
Kind Code:
A1
Abstract:
[Problem] [Solution] Provided is a phosphor composition which contains a phosphor, a matrix resin and metal compound particles, and which is characterized in that: the metal compound particles have a refractive index of 1.7 or more and an average particle diameter of 1-50 nm; the average refractive index (N1) of the metal compound particles and the matrix resin and the refractive index (N2) of the phosphor satisfy the relation described below; and the metal compound particles are grafted. A sheet is able to be formed by a single coating process using this phosphor composition, and this phosphor composition is capable of improving the luminance of an LED package that employs this phosphor composition. 0.20 ≥ |N1 - N2|
