Near-infrared-to-visible photon upconversion via triplet-triplet annihilation of a solid-state system fabricated by rapid drying casting

摘要

NIR-to-Vis (from 785 nm to ~570 nm) TTA photon upconversion was developed in a binary solid that was fab-ricated by the rapid drying casting. The UC characteristics of the individual microparticles of the system were evalu-ated under microscopy. The elementary processes were investigated by time-resolved/steady-state spectroscopies.
