Netherlands: PhD Ultrafast spectroscopy on metal-organic frameworks at Delft University of Technology

Font size: Decrease font Enlarge font

Job description

Metal-organic frameworks (MOFs) are hybrid, crystalline materials consisting of inorganic and organic building blocks. MOFs are of interest for application in catalysis, storage, separation, sensing and opto-electronic devices such as MOF-based light-emitting diodes (MOF-LEDs). The current project is a collaboration between Delft University of Technology and Philips Research.
Recent MOF research at TU Delft has led to the development of an electroluminescent MOF-based device that can be cast in flexible sheets with light emission over a large surface area. The source of the phenomenon is not clear.
In this research project, two researchers will closely collaborate with each other and the industrial partner to (1) gain a fundamental understanding of the observed electroluminescent behaviour and (2) further develop the composite material from a synthetic, characterisation and device manufacturing point of view.
For topic (1) we seek a candidate to study the nature and dynamics of photoexcited states and charge carriers with femtosecond and nanosecond pump-probe laser techniques, including microwave and terahertz conductivity measurements. In addition, experiments will be performed using ultrashort, high-energy electron pulses from an accelerator. These are unique combinations of techniques that are present at Delft University of Technology. The aim is to elucidate the mechanism of electricity-to-light conversion in new, MOF-based composites and to optimise the performance of LEDs.


Are you an enthusiastic researcher with a relevant MSc degree in Physics, Chemistry or Chemical Engineering? Then we might be looking for you! We are looking for a flexible teamplayer capable of communicating with people in the various disciplines involved in this challenging project. You have a pro-active, independent, problem-solving and result-oriented work attitude. You will be able to work in a team as well as independently. You will publish results in peer-reviewed scientific journals, participate in international conferences and write a PhD thesis.

Conditions of employment

TU Delft offers an attractive benefits package, including a flexible work week, free high-speed Internet access from home (with a contract of two years or longer), and the option of assembling a customised compensation and benefits package. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities.
As a PhD candidate you will be enrolled in the TU Delft Graduate School. TU Delft Graduate School provides an inspiring research environment; an excellent team of supervisors, academic staff and a mentor; and a Doctoral Education Programme aimed at developing your transferable, discipline-related and research skills. Please for more information]]]

Delft University of Technology

Delft University of Technology (TU Delft) is a multifaceted institution offering education and carrying out research in the technical sciences at an internationally recognised level. Education, research and design are strongly oriented towards applicability. TU Delft develops technologies for future generations, focusing on sustainability, safety and economic vitality. At TU Delft you will work in an environment where technical sciences and society converge. TU Delft comprises eight faculties, unique laboratories, research institutes and schools.


Applied Sciences

The mission of the Department of Chemical Engineering (ChemE) is to generate knowledge and educate people in the area of nano-chemical engineering to improve the quality of life for a sustainable society, focusing on energy, water, health and the environment.

The Opto-Electronic Materials section is part of the Chemical Engineering Department of the Faculty of Applied Sciences. Our key interest is studying the nature and dynamics of short-lived, intermediate excited states (excitons) and charge carriers within complex materials such as functional polymers, self-assembling molecular aggregates, inorganic nanoparticles, inorganic/organic composites and DNA.
