STARKVILLE, Miss.ā°®°®Ö±²„ researchers are honing in on next-generation LED technology with a $708,506 grant from the U.S. Department of Energy to study tailoring the brightness of lead halide perovskitesāsolid-state inorganic materialsāwhich show promise in LEDs, solar cells and photodetectors.
Mahesh K. Gangishetty, an °®°®Ö±²„ assistant professor with appointments in both the Department of Chemistry and the Department of Physics and Astronomy, leads the three-year grant in collaboration with co-principal investigator Neeraj Rai, an °®°®Ö±²„ professor of chemical engineering. The funding source is the DOE Office of Scienceās Basic Energy Sciences program.
āLead halide perovskites are emerging hybrid materials forĀ solid-stateĀ lightingāLEDs in display and lightingāapplications,ā said Gangishetty. āThe presence of small impurity metal ions makes them brighter. This work allows us to seek insight into where these impurities are located and how they are connected inside the lattice to unfold the mystery of the origin of enhanced brightness.āĀ
Rai said the global market for micro-LED display technologyāāfound in cellphones and TV screensāāis currently valued at several hundred million dollars and projected to grow to over $30 billion by 2030.
āThere is a need for abundant, low-cost, and easily processable materials for future display and lighting applications,ā Rai said. āPerovskites show great potential for high-resolution displays by emitting pure and desirable colors. This funding allows us to develop a fundamental understanding of their structure that helps make the material brighter and more efficient for next-generation LED technology.ā
