Low-dimensional metal halide perovskite emitters, ranging from strongly-confined quantum dots and nanoplatelets to weakly-confined nanocrystals, have emerged as promising materials in advanced display, lasing and quantum technology, offering superior tunability, solution processibility, and outstanding optoelectronic properties.
This symposium will highlight breakthroughs in synthesis, photophysics, and applications of these low-dimensional perovskite emitters, aiming to build a comprehensive understanding of their unique optical and electronic properties. A particular emphasis will be placed on the fundamental photophysics of these low dimensional emitters, exhibiting different properties as their bulk counterparts, including exciton dynamics, self-assembled superstructures with collective behaviours, and emission at single particle level.
Discussions will also cover strategies to mitigate non-radiative losses and enhance operational stability via new synthesis and surface modification strategies, which remain major bottlenecks for commercial viability. We invite contributions on both experimental and theoretical approaches, with interest in topics such as light-emitting diodes, lasers, single-photon sources, and polarized emission. The symposium seeks to foster dialogue across disciplines, bridging chemists, spectroscopists, and photonic and device scientists, and aims to advance the frontiers of research in low-dimensional perovskite emitting systems

Maria Chamarro is Professor in Physics at Sorbonne University, France and member of the Paris Institute of Nanosciences (INSP). She received her PhD in Physics (Optics speciality) form Zaragoza University, Spain, in 1989. Since 2021 she is a member of the French Committee for Scientific Research (five years) a position that she already occupied in the previous years (1995-2000). From 2012 to 2014 she was member of ‘Directory of Research’ at Pierre and Marie Curie University (now Sorbonne University). Her area of expertise is the experimental study of condensed matter electronic properties. In particular, she was interested in the spectroscopy of glasses doped with transition metals or rare earths, and the optical properties and relaxation dynamics of electronic excitations in semiconductor nanostructures. She was co-head of the "Spin Dynamics" team at INSP where she worked in the optical orientation and the all-optical manipulation of electron spin confined in a semiconductor quantum dot. In this framework, she developped ultrafast optical spectroscopies based on the photo-induced Faraday and Kerr effects. Now she coordinates a research project centred on the study of perovskite nanocrystals for nanophotonics applications.
