Abstract
An organic-inorganic perovskite satisfying ET<ET1 and ES-ET≤0.1 eV has a high emission efficiency. ES represents the excited singlet energy level in emission of an inorganic component, ET represents the excited triplet energy level in emission of an inorganic component, ET1 represents the excited triplet energy level in emission of an organic component.
