LUMINESCENT COMPOSITION AND LIGHT-EMITTING ELEMENT USING SAID COMPOSITION

摘要

A luminescent composition comprising a luminescent organic compound and a conjugated polymer compound having a luminescence maximum further toward the short wavelength end than the luminescence maximum of the luminescent organic compound at 350 nm to 500 nm, and satisfying the following formula (1); f g h × w ‰¥ 0.04
in the formula,
f(g, h) represents the convolution integral of the emission spectrum of the conjugated polymer compound and the gram absorption coefficient spectrum of the luminescent organic compound (L/g·cm) in the range of 200 nm to 800 nm, in 1 nm steps, and
w represents the content of the luminescent organic compound where the total content of the luminescent organic compound and conjugated polymer compound in the luminescent composition is defined as 1 part by mass.
