The energy of visible photons and the accessible redox potentials of common photocatalysts
set thermodynamic limits to photochemical reactions that can be driven by traditional visible …

Multiresonance thermal activated delayed fluorescence (MR-TADF) materials with an
efficient spin–flip transition between singlet and triplet excited states remain demanding …

Near-infrared-to-visible photon upconversion holds great promise for a diverse range of
applications. Current photosensitizers for triplet-fusion upconversion across this spectral …

Organic semiconductor materials have been widely used in various optoelectronic devices
due to their rich optical and/or electrical properties, which are highly related to their excited …

Abstract Ultraviolet (UV, λ< 400 nm) light is essential for various photochemical reactions,
but its intensity in the solar spectrum is very low, and light sources that artificially generate …

Two-photon polymerization (TPP) currently offers the highest resolution available in 3D
printing (∼ 100 nm) but requires femtosecond laser pulses at very high peak intensity (∼ 1 …

Triplet–triplet annihilation photon upconversion (TTA-UC) is a process in which triplet
excitons combine to form emissive singlets and holds great promise in biological …

Photoactive complexes with earth-abundant metals have attracted increasing interest in the
recent years fueled by the promise of sustainable photochemistry. However, sophisticated …

All photovoltaic solar cells transmit photons with energies below the absorption threshold
(bandgap) of the absorber material, which are therefore usually lost for the purpose of solar …
