Low-dimensional perovskites for light-emitting applications: What do we need and how to make it?

>>Join via Zoom.

Jawaher Almutlaq, Postdoctoral Fellow
Research Laboratory of Electronics

The first part of this talk covers the controversy regarding the origin of emission in zero-dimensional perovskites (0D), Cs4PbBr6 and Cs4PbI6, through a comparative analysis between 0D and three-dimensional (3D) perovskites.

Then, Almutlaq will address the shortcoming of lead-based perovskites in terms of toxicity and stability, motivated by the high demand for sustainable materials with analogous electrical and structural properties. Finally, Almutlaq will share the recent work on CsMnBr3 NCs, which reveals an intense red PL peak, a high PLQY with a remarkable excitation spectrum and surprisingly short lifetime. This work paves the way for finding sustainable materials for the next generation of light-emitting applications.
