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…
Room-temperature cavity exciton-polariton condensation in perovskite quantum dots
Ioannis Georgakilas, David Tiede, Darius Urbonas +13
The exploitation of the strong light-matter coupling regime and exciton-polariton condensates has emerged as a compelling approach to introduce strong interactions and nonlineariti…
Perovskite nanocrystal self-assemblies in 3D hollow templates
Etsuki Kobiyama, Darius Urbonas, Maryna I. Bodnarchuk +7
Highly ordered nanocrystal (NC) assemblies, namely superlattices (SLs), have been investigated as novel building blocks of optical and optoelectronic devices due to their unique pr…
Phonon-driven wavefunction localization promotes room-temperature, pure single-photon emission in large organic-inorganic lead-halide quantum dots
Leon G. Feld, Simon C. Boehme, Sebastian Sabisch +13
In lead halide perovskites (APbX3), the effect of the A-site cation on optical and electronic properties has initially been thought to be marginal. Yet, evidence of beneficial effe…
Circularly Polarized Luminescence Without External Magnetic Fields from Individual CsPbBr3 Perovskite Quantum Dots
Virginia Oddi, Chenglian Zhu, Michael A. Becker +8
Lead halide perovskite quantum dots (QDs), the latest generation of colloidal QD family, exhibit outstanding optical properties which are now exploited as both classical and quantu…
