Efficient red-green-blue primary luminescence with exceptional narrowband and high durability is essential for cutting-edge display applications. We propose a paradigm of electronic donor/acceptor “core-shell” modulation in a multiple-resonance skeleton, utilizing the intramolecular charge transfer to achieve wavelength tuning from 447 to 624 nm (~0.8 eV) with excellent device stability.
