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

摘要

[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|
