The Photochemical Reactions of Dirhenium Decacarbonyl With Water and of Dinuclear Rhenium Carbonyl Complexes Substituted by Nitrogen Bases
… produced selectively under 313 nm irradiation; quantum yield measurements at this wavelength indicate that formation of the aqua complex proceeds through dissociative substitution of H(,2)O for CO in photogenerated Re(CO)(,5)(.). The first order rate constant for CO loss from Re(CO)(,5)(.) is …

Fabrication and optimization of light emitting devices with core-shell quantum dots
Quantum dot light emitting devices (QD-LEDs) are promising options for the next generation of solid state lighting, color displays, and other optoelectronic applications. Overcoating quantum dots (QDs) -- semiconducting nanocrystals of CdSe, PbS, or another similar compound -- with a wide band-gap …

Charge Carrier Balance in Lead Halide Perovskite Light Emitting Diodes
… balance is directly related to the External Quantum Efficiency (EQE), and is thought to have additional effects on device endurance and stability. In this thesis I present a series of experiments and simulations to study the charge balance in Lead Halide Perovskite (LHP) emitter LEDs. These …
