Skrabalak and Georgescu Groups Receive NSF DMR Solid State Chemistry Grant to study Photoluminescent Bismuth Lone Pair Materials

August 21, 2025

Happy to share that Sara Skrabalak and myself have been awarded a new NSF DMR Solid State Chemistry grant for our collaborative project on photoluminescent oxyhalides with bismuth lone pairs! πŸŽ‰

This achievement would not have been possible without the incredible contributions of our students πŸŽ‰ . From left to right:

-Emily Ward (undergraduate, co-advised with Sara, now pursuing her Ph.d at Princeton) introduced these materials and the role of lone pairs to our group, then developed the first Wannier-based Hamiltonian and representation of lone pairs in a solid ( https://lnkd.in/gb7_fMBA )
-Varsha Kumari (Ph.D. student, co-advised) laid the foundation for much of the theoretical framework behind our proposal, taught me about photoluminescence in these materials, and began her own direction in both simulations and measurements.
-Nayana Christudas Beena (in Sara’s group, who is applying for postdocs, so you should reach out to her 😊 ) has driven forward the experimental exploration of these materials while making our team discussions more rigorous, as well as helped mentor Emily since she started college.
-Connor Schulte (in Sara's group) contributed important preliminary results that helped shape this direction.

I am especially grateful to Emily and Varsha for trusting me enough to work with me before I even had a research group of my own, and for setting the stage for the outstanding students who have since joined our group.

This project allows us to continue supporting and training excellent students , who are pushing science forward! πŸŽ‰
