Are you eager to apply advanced laser spectroscopies to develop the next generation of photothermal materials for applications such as sunscreen filters and molecular heaters? Do you enjoy to get the most out of the equipment you’re working with? Then this is the job for you!
Light-to-heat conversion materials generate great interest due to their widespread applications. Amongst these is photoprotection against the harmful effects of UV radiation, which is presently attracting increasing attention because of concerns regarding adverse health and environmental effects of currently used sunscreen filters. Closely related to such materials are molecular heaters that employ heat -the ‘by-product’ produced by photon absorption- to enhance growth in agri- and horticulture. As yet, mainly empirical, brute-force approaches have been applied to develop new materials. We have shown that a bottom-up approach in which a full and detailed understanding of the photophysics and photochemistry of promising leads is obtained by molecular laser spectroscopy, enables the rational development and tailoring of such materials.What are you going to do?
You will use high-resolution nanosecond laser spectroscopic technologies to determine the spectroscopic properties and excited-state dynamics of mostly naturally occurring compounds that serve as a starting point for further optimization. Together with one of the group technicians you will further optimize the molecular beam spectrometer that has recently become operational, and that is based on photoelectron Velocity Map Imaging. Apart from gas-phase studies you will also perform studies under ‘as-used’ non-isolated conditions. Such studies focus primarily on following in real time the excited-state dynamics using femtosecond pump-probe spectroscopies as well as the dynamics occurring on the electronic ground state after dissipation of the photon energy using techniques such as nanosecond transient absorption spectroscopy. You will support the interpretation of your experimental results with the results of quantum chemical calculations. Based on the inputs from gas-, solution- and in-silico studies, you will propose and study new compounds with improved properties that will be synthesized by the chemical analyst of the group.You will/tasks:
