The field of colloidal synthesis of semiconductors emerged 40 years ago and has reached a
certain level of maturity thanks to the use of nanocrystals as phosphors in commercial …

The properties of colloidal quantum-confined semiconductor nanocrystals (NCs), including
zero-dimensional (0D) quantum dots, 1D nanorods, 2D nanoplatelets, and their …

An ensemble of emitters can behave very differently from its individual constituents when
they interact coherently via a common light field. After excitation of such an ensemble …

The easily tunable emission of halide perovskite nanocrystals throughout the visible
spectrum makes them an extremely promising material for light-emitting applications …

Current colloidal synthesis methods for CdSe nanoplatelets (NPLs) routinely yield samples
that emit, in discrete steps, from 460 to 550 nm. A significant challenge lies with obtaining …

Polarized light is critical for a wide range of applications, but is usually generated by filtering
unpolarized light, which leads to substantial energy losses and requires additional optics …

Intrinsically directional light emitters are potentially important for applications in photonics
including lasing and energy-efficient display technology. Here, we propose a new route to …

Low‐dimensional metal‐halide perovskites have exhibited significantly superior nonlinear
optical properties compared to traditional semiconductor counterparts, thanks to their …

Compared with zero‐dimensional quantum dots and one‐dimensional nanorods, two‐
dimensional nanoplatelets exhibit many unique optical properties. Due to strong quantum …

By implementing four-wave mixing (FWM) microspectroscopy, we measure coherence and
population dynamics of the exciton transitions in monolayers of MoSe2. We reveal their …
