WELCOME TO THE SPECTROSCOPY AND DYNAMICS GROUP
WELCOME TO THE SPECTROSCOPY AND DYNAMICS GROUP
Our research interest involves utilization of various spectroscopic, microscopic and electrochemical techniques to address challenging problems in the field of chemistry, materials and biology.
We extensively apply steady-state and time-resolved fluorescence, and transient absorption spectroscopy to provide key insights into light-matter interactions, heterogeneity and solvation properties of various advanced optical and energy materials.
From the spectroscopic studies we seek to understand primarily to aspects: (1) light harvesting (light absorption and energy transfer) and (2) electron transfer dynamics of the materials in solution and on solid substrates.
The kind of optical and energy materials that our group is currently focusing on for synthesis and spectroscopic characterizations include but not limited to:
- Excitonic materials of strongly coupled dye aggregates
- Hybrids of dye-aggregates and inorganic nanomaterials
- Organic donor-acceptor charge transfer materials
- Plasmon-exciton coupled (plexciton) materials
- Perovskite materials
- Nano-biohybrid materials
Based on the knowledge gained from spectroscopic studies, we try to find suitability of some of our designed materials in various applications.
Our research group is constantly making efforts to explore materials applications in biosensing, white light generation, photo(electro)catalysis for water splitting, hydrogen generation and photocatalytic organic reactions, photovoltaic solar and fuel cells.
Application part of the research is challenging as it requires to control multiple parameters particularly when it comes to the applications in photovoltaic (solar cell) and photoelectrochemical (water splitting and fuel cell) devices.
In addition to design, synthesis and opt-electronic characterizations of materials (organic, inorganic and organic-inorganic hybrid) and their applications in light harvesting and energy conversion technologies, our group is also focusing on understanding the dynamics of protein aggregation/fibrillation under different newly designed and synthesized molecular agents.
