研究领域

Physical Inorganic Chemistry

Research in the Gamelin group combines the use of synthetic, spectroscopic, magnetic, magneto-optical, and photoelectrochemical experiments to advance the development of new multifunctional inorganic materials for spintronics and energy conversion technologies. This research has components of inorganic, physical, and materials chemistries as well as nanoscience and nanotechnology. Our research emphasizes application of a diverse array of complementary physical techniques to probe the electronic structures and physical properties of the new materials we develop. Core experiments include electronic absorption, magnetic circular dichroism (MCD), photoluminescence, photocurrent action, and electron paramagnetic resonance (EPR) spectroscopies, all over broad temperature ranges and most with fast time resolution. Experimental results are complemented by theoretical analyses using core traditional physical-inorganic approaches like ligand field theory, as well as by first principle density functional approaches. A central research theme is the development of new photoactive inorganic materials on nanometer length scales. Typical projects involve iteration between materials synthesis and advanced physical characterization to achieve and optimize the target physical properties. The group's interdisciplinary research approach allows relationships between synthesis, electronic structure, magnetism, photomagnetism, photocatalysis, and other physical properties to be explored deeply from multiple perspectives, enriching our understanding of both fundamental and applied aspects. Recently investigated physical properties include spontaneous photomagnetization, photodoping, exciton storage, spin-dephasing, photoconductivity, and solar photoelectrochemical water oxidation.
