Transition between cooperative emission regimes in giant perovskite nanocrystals
Etsuki Kobiyama, Gabriele Rainò, Yuliia Berezovska +6
Interactions between emitters within an ensemble can give rise to cooperative processes that significantly alter the properties of the emitted light. One such process is superfluor…
Long Exciton Dephasing Time and Coherent Phonon Coupling in CsPbBrCl Perovskite Nanocrystals
Michael A. Becker, Lorenzo Scarpelli, Georgian Nedelcu +7
Fully-inorganic cesium lead halide perovskite nanocrystals (NCs) have shown to exhibit outstanding optical properties such as wide spectral tunability, high quantum yield, high osc…
Superfluorescence from Lead Halide Perovskite Quantum Dot Superlattices
Gabriele Rainò, Michael A. Becker, Maryna I. Bodnarchuk +3
An ensemble of emitters can behave significantly different from its individual constituents when interacting coherently via a common light field. After excitation, collective coupl…
Bright triplet excitons in lead halide perovskites
Michael A. Becker, Roman Vaxenburg, Georgian Nedelcu +13
Nanostructured semiconductors emit light from electronic states known as excitons[1]. According to Hund's rules[2], the lowest energy exciton in organic materials should be a poorl…
