Field of Research Interest

My research interests lie in the development and application of fluorescent nanomaterials, including nanoparticles, quantum dots, and two-dimensional (2D) nanostructures, as well as organic molecules, organic polymers, organometallic compounds and light-emitting devices, e.g., OLEDs and QLEDs. A major focus of my work is the design of advanced optical probes and sensors for the sensitive detection and monitoring of hazardous and explosive substances in the environment, utilizing nanomaterials such as quantum dots and nanosheets.

To investigate the photophysical and optoelectronic properties of these systems, I employ a range of highly sensitive spectroscopic techniques, including steady-state and time-resolved fluorescence spectroscopy, electric-field modulation spectroscopy, and transient absorption spectroscopy along with other complementary experimental methods.
