Title:
LIGHT-ACCUMULATING COMPOSITION, LIGHT-ACCUMULATING ELEMENT AND WAVELENGTH CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2019/031524
Kind Code:
A1
Abstract:
An organic light-accumulating composition which contains at least a first organic compound, a second organic compound and a third organic compound, while satisfying formula (1) constitutes a light-accumulating material that is easily controlled in terms of the luminescent color. ES1(B) - ES1(A) ≤ 0.15 eV Formula (1) In the formula, ES1(A) represents the lowest excited singlet energy level of light emission by means of the first organic compound and the second organic compound; and ES1(B) represents the lowest excited singlet energy level of the third organic compound.
