Advanced organic materials represent a very interesting alternative to traditional inorganic substances used in photonic applications. Organic materials provide a number of potential advantages such as flexibility, low weight, preparation with low-cost material printing techniques, wide range of parameter tuning, low environmental impact, etc. This work will deal with the study of the relationship between (especially) optical properties and the chemical structure of organic pi-conjugated molecules (dyes, pigments). The findings will be useful in applications such as light-emitting devices (OLED), solar cells, organic solid-state lasers, fluorescent markers for the study of biological systems, etc. Part of the work will be the preparation and study of model devices for selected applications. Typical methods of study will include absorption and fluorescence spectroscopy, determination of fluorescence lifetime and quantum yields, and determination of threshold excitation energy to induce amplified spontaneous emission (ASE) and other parameters affecting their function. The work will take place within the Laboratory of Organic Electronics and Photonics (https://www.fch.vut.cz/vav/cmv/laboratore/elektro) at the Center for Materials Research at the Faculty of Chemistry, Brno University of Technology. Within this team, we have more than 20 years of experience in this field, evidenced by almost 200 publications.
