Our research

on light and material interaction

Light and color have an influence to our daily lives. We perceive color when different wavelengths of light are interfered by the object which we look at. We are fascinated by the richness of the full electromagnetic spectrum in which we can harness the different frequencies and energies of light to study a wide variety of optical phenomena. With a group of interdisciplinary researchers, we aim to perform spectroscopic studies on materials, gas molecules, pigments in order to design and to develop optical-based applications.

Functional optical coatings

We aim to develop both optical and colorimetric sensors that can be utilized for specific applications. These include the design, simulation and fabrication of optical components, optical coatings that operate in the wavelength range between visible up to mid-infrared.

Functional materials development

We develop and synthesize responsive materials (temperature, pH, moisture, specific gases etc.) that can be used for sensing application. The research includes responsive polymer synthesis, functionalization of polymers, characterization, fabrication of electrodes for electronic sensing, sensor fabrication and sensor characterization.

Spectroscopic studies

By performing spectroscopic studies on the materials, we gain in-depth knowledge on the intrinsic properties of the materials like their oscillator strength, transmission, and their vibrational modes. Concentration, kinetic, and spectral shifts are some of the studies conducted within the group to explain the optical phenomena we observe. Read more...
