David F. Kelley

Professor David F. Kelley is a faculty member at the University of California, Merced, specializing in physical chemistry and quantum dot spectroscopy. His research focuses on ultrafast optical spectroscopy of semiconductor nanoparticles, particularly InP/ZnSe and CdSe-based quantum dots and nanoscale materials. He has active collaborations with industry partners like Nanosys Inc. and secures grants from the U.S. Department of Energy for quantum dot development.

Research highlights include:

• Investigating Auger recombination mechanisms in quantum dots under high photon flux and elevated temperatures
• Examining lattice mismatch effects on shell morphology in core/shell nanocrystals
• Studying exciton dynamics in two-dimensional CdSe nanoplatelets
• Exploring GaSe nanoparticle aggregation and liquid crystal integration

His publications (1980-2024) demonstrate expertise in surface passivation, carrier relaxation, and quantum confinement effects. Current projects involve DOE-sponsored development of InP-based quantum dots for solid-state lighting applications.
