Energy Transfer in Nanodroplet‐Based Luminescent Solar Concentrators
Small, EarlyView.We present novel luminescent solar concentrators (LSCs) featuring polymer composites with fluorescent dye‐doped oil nanodroplets. This liquid environment ensures high dye solubility and preserves fluorescence quantum yields, even at high local dye concentrations.

Small, EarlyView.This work reports a differentiated ion‐doping strategy to engineer the self‐trapped exciton emission of CsPbBr3@CsPb2Br5 nanostructures, in which bright orange emission is obtained by the dissolution and recrystallization of Cu:CsPbBr3 in water. Lattice‐incorporated Cu components create self‐trapped exciton centers because of bright green emission ...

High Voltage, EarlyView.ABSTRACT Data from five rocket‐triggered lightning flashes are adopted to analyse the correlated transient response of buried cables and lightning channel radiations. These five flashes have the same termination point that is right above the buried cables and involve a total of 32 return strokes.
