Binary and ternary metal telluride nanocrystals for mid-IR applications
Transition-metal tellurides offer a unique platform for realizing new semiconductor and semi-metallic materials for biomedical devices and laser applications in the infrared ranges. They exhibit a high level of flexibility to achieve tunable band gaps through structural and compositional control. This project investigates the band gaps and photoluminescence of various new transition-metal tellurides through a materials characterization perspective and is conducted in close collaboration with the Air Force Research Laboratory. Materials characterization of novel transition-metal tellurides based on UV-vis spectroscopy, dynamic light scattering, and photoluminescence spectroscopy are reported for the chalcogenide nanocrystals to understand their novel structure-property relations. Controlled band gap and emission peaks were achieved by experimentally changing the composition of the chalcogenide nanocrystals. These results will provide key experimental insights for achieving new materials for mid-IR range device applications.
