Photon upconversion, the process of converting low-energy photons to higher energy ones, shows promise for applications in solar energy, photocatalysis, biomedicine, and additive manufacturing. In tri...

Halide perovskite nanocrystals are promising materials for optoelectronic applications. Metal doping provides an avenue to boost their performance further, e.g., by enhancing light emission, or to pro...

The structural and photophysical properties of the 2D layered metal halides (4F-PMA)2GeI4 and (4F-PMA)2PbI4 are reported. For the Ge composition, reduced exciton-phonon coupling is found and the abse....

Endowing chirality onto solution-processable semiconductors unlocks new bounds for their spin and optoelectronic properties. This Review discusses the synthesis, properties, characterization methods, ...
