Abstract

The typical triplet sensitizer Pd(II)octaethylporphyrin (PdOEP) was first found to possess absorption involving a hot vibrational energy-level, resulting in one-photon absorption (OPA) upconversion emission. Cascading hot-band OPA and triplet–triplet annihilation upconversion (TTA-UC) provides a novel low-powered upconversion approach that can effectively enhance the anti-Stokes shift in a simple way.
