Metal-halide perovskites have rapidly emerged as one of the most promising materials of the
21st century, with many exciting properties and great potential for a broad range of …

Ultrafast optical microscopy, generally employed by incorporating ultrafast laser pulses into
microscopes, can provide spatially resolved mechanistic insight into scientific problems …

The key to advancing lithium-ion battery technology—in particular, fast charging—is the
ability to follow and understand the dynamic processes occurring in functioning materials …

Strong-coupling between excitons and confined photonic modes can lead to the formation of
new quasi-particles termed exciton-polaritons which can display a range of interesting …

Although sulfide perovskites usually require high-temperature syntheses, we demonstrate
that organosulfides can be used in the milder syntheses of halide perovskites. The …

Semiconductor nanoplatelets (NPLs), with their large exciton binding energy, narrow
photoluminescence (PL), and absence of dielectric screening for photons emitted normal to …

We image charge carrier transport over nanometers–micrometers and picoseconds–
microseconds in halide double perovskites Cs2AgBiBr6 and Cs2AgTlBr6 single crystals …

Conspectus Following the impressive development of bulk lead-based perovskite
photovoltaics, the “perovskite fever” did not spare nanochemistry. In just a few years …

One-dimensional (1D) colloidal lead halide perovskites (LHPs) have potential as quantum
emitters. Their study, however, has been hampered by their previous instability, leaving a …

The Rashba effect has been proposed to give rise to a bright exciton ground state in halide
perovskite nanocrystals (NCs), resulting in very fast radiative recombination at room …
