LED LED 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

A phosphor composition comprising a phosphor, a matrix resin, and metal compound particles, wherein the refractive index of the metal compound particles is 1.7 or more, the average particle diameter is 1 to 50 nm, and the average refractive index of the metal compound particles and the matrix resin. (N1) satisfies the following relationship with the refractive index (N2) of the phosphor, and the metal compound particles are grafted, so that the sheet can be produced by one coating process using a phosphor composition or the like, and this is applied. It provides a phosphor composition that can improve the brightness of the LED package. 0.20≥ | N1-N2 |
