Abstract

energy level allows coupling with the cyan-emitting annihilator 9,10-bis(phenylethynyl)anthracene, achieving a significant anti-Stokes shift from 808 nm excitation to 480 nm emission-an advancement not previously realized in NIR-excited QD-based TTA-UCs. This work provides a new opportunity, from the perspective of ligand design, to enhance quantum dot-based upconversion performance and expand the TTA-UC anti-Stokes shift using QDs into the cyan blue region, thereby advancing the development of efficient and stable upconversion materials.
