STARKVILLE, Miss.鈥擬ississippi 性视界传媒 University 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 perovskites鈥攕olid-state inorganic materials鈥攚hich show promise in LEDs, solar cells and photodetectors.

Mahesh K. Gangishetty, an 性视界传媒 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 性视界传媒 professor of chemical engineering. The funding source is the DOE Office of Science鈥檚 Basic Energy Sciences program.

鈥淟ead halide perovskites are emerging hybrid materials for聽solid-state聽lighting鈥擫EDs in display and lighting鈥攁pplications,鈥 said Gangishetty. 鈥淭he 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.鈥澛

Rai said the global market for micro-LED display technology鈥撯揻ound in cellphones and TV screens鈥撯搃s currently valued at several hundred million dollars and projected to grow to over $30 billion by 2030.

鈥淭here is a need for abundant, low-cost, and easily processable materials for future display and lighting applications,鈥 Rai said. 鈥淧erovskites 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.鈥
