Month: September 2024

The group warmly welcomes a new visiting postdoc fellow Dr. Jing Li and a
SERB-OVDF fellow Avija Ajayakumar joining us. Jing received his PhD from Dalian University of Technology with Prof. Yiming Yang; Avija is currently a PhD student at National Institute For Interdisciplinary Science and Technology (NIIST) with Dr. Vijayakumar Chakkooth. Both of them will spend a year with us. Welcome to the group. Look forward to working together!

Kang’s work on two-dimensional-lattice-confined single-molecule-like aggregates has been published in Nature. Congratulations!

We discovery an unprecedented phase of molecular aggregate that forms in a two-dimensional hybrid perovskite superlattice with a near-equilibrium distance, which we refer to as a single-molecule-like aggregate (SMA). By implementing two-dimensional superlattices, the organic emitters are held in proximity, but, surprisingly, remain electronically isolated, thereby resulting in a near-unity photoluminescence quantum yield, akin to that of single molecules! Moreover, the emitters within the perovskite superlattices demonstrate strong alignment and dense packing resembling aggregates, allowing for the observation of robust directional emission, substantially enhanced radiative recombination and efficient lasing.

This work is highlighted by Purdue, Notre Dame, etc.

Our undergrad student Anika and her work on perovskite solar cells, semiconductors, and simulations are being highlighted in the Purdue News — Celebrating 150 years of Purdue engineering excellence. Congratulations! Read the story here.
