Chemistry of Materials and the ACS Division of Inorganic Chemistry are proud to announce that Shruti Hariyani, Graduate Student and Research Assistant at the University of Houston and Jakoah Brgoch, Associate Professor at the University of Houston, and Principal Investigator in the Texas Center for Superconductivity, are the winners of the 2021 Chemistry of Materials Lectureship and Best Paper Award. The award honors the authors of an article published in 2020 that has outstanding influence across the field of materials chemistry, while also recognizing that research is a team endeavor.
The winning paper, “Local Structure Distortion Induced Broad Band Emission in the All-Inorganic BaScO2F:Eu2+ Perovskite” exemplifies the power of using computation and experiment to gain a deeper understanding of how local distortions can impact a material’s properties. “An important takeaway is that low concentrations of rare-earth dopants can affect the local structure of the host material, which should have a significant impact on the design of future phosphor materials,” says Sara E. Skrabalak, Editor-in-Chief of Chemistry of Materials.
Referencing the teamwork aspect of the award, Skrablak notes that “The nomination materials also highlighted creative problem-solving and effective mentoring as Shruti learned how to conduct advanced calculations via Zoom meetings with Professor Brgoch during laboratory shutdowns. This training has been a springboard for Shruti, who is now collaborating with other groups on understanding different phosphor systems.”

What does winning this award mean to you?
It is an absolute delight to have our work selected out of so many outstanding research papers published in Chemistry of Materials. We have spent a significant amount of time trying to deepen our understanding of the fundamental structure-composition-property relationships that govern luminescent materials.
This project provided an incredible, albeit sometimes frustrating, opportunity to understand how local structure influences the optical properties. This award validates all of our efforts.
We hope that having our work highlighted by the award will encourage researchers to critically consider the importance of local structure in bulk materials. Of course, we are also grateful to have financial support for this project from the Welch Foundation and the NSF that allowed us to answer this fundamental chemistry problem.
This award is about teamwork. How did working with each other lead to the results achieved and described in your article?
This project started by trying to understand bizarre optical properties in what should have been a simple system. We came up with a series of synchrotron scattering experiments to address our questions, but then COVID-19 closed our lab.
Fortunately, we were able to pivot and draw on our group’s background in computation to come up with a solution. Shruti is an outstanding graduate student, and we relentlessly bounced ideas off of each other while working from home to determine a possible local distortion mechanism that described exactly what we were seeing.
Stay tuned for details about the upcoming Chemistry of Materials Lectureship and Best Paper Award symposium during the ACS Fall National Meeting.
