International audience; In the current context of rising popularity of perovskites as excellent materials for optoelectronics, inorganic lead halide perovskite (CsPbX3, X=Cl, Br, I) quantum dots constitute a promising platform for light emitting devi

Narrow emission is desired for light-emitting devices. Here, Kovalenko et al. demonstrate that the emission line-broadening in perovskite quantum dots is dominated by the coupling between excitons and surface phonon modes which can be controlled by m

Abstract Supramolecular assemblies from organic dyes forming J‐aggregates are known to exhibit narrowband photoluminescence with full‐width at half maximum of ≈9 nm (260 cm−1). Applications of these high color purity emitters, however, are ha
