Research

Physical and Inorganic Chemistry

Colloidal semiconductors nanoparticles have been the focus of much research due to their uniquely tunable electronic properties. However, surface traps result in short carrier diffusion lengths and poor charge extraction efficiencies. Traditionally, the passivation of surface traps has been approached by modifying core-shell architectures.  My research focuses on establishing the role of Mn2+ doping as an alternate method to prolong charge carrier lifetimes. I use transmission electron microscopy, electron paramagnetic resonance spectroscopy, absorbance spectroscopy, fluorescence spectroscopy, transient absorption spectroscopy, steady state and time resolved photoluminescence spectroscopy, and dynamic light scattering to both characterize and study electron transfer in ZnSe Mn2+ nanoparticles.
