PhD: Photochromism in Oxyhydrides

Department/faculty: Applied Sciences
Level: Master degree
Working hours: 38 hours per week
Contract: 4 years
Salary: €2222 to €2840

Applied Sciences

The Faculty of Applied Sciences is the largest faculty of TU Delft, with around 550 scientists, a support staff of 250 and 1,800 students. The faculty conducts fundamental, application-oriented research and offers scientific education at the bachelor, master and doctoral levels. The faculty is active in the fields of Life and Health Science & Technology, Nanoscience, Chemical Engineering, Radiation Science & Technology, and Applied Physics.

Within the Chemical Engineering Department of the Faculty of Applied Sciences, the Materials for Energy Conversion and Storage (MECS) section develops new materials for sustainable energy applications. Current research activities include hydrogen storage materials, hydrogen sensors, photocatalysis and photo-electrochemistry, core-shell quantum dots for next-generation photovoltaics, and materials for CO2 capture and sequestration.

Job description

Recently, the unique photochromic properties of YOH were discovered. Unlike other photochromic materials, these materials darken over a large fraction of the solar spectrum upon illumination. The contrast is large, and UV is not required for the excitation. This makes these materials optimally suited for the inside of double glazed window panes. However, the bleaching of the photodarkened material is slow. To solve this problem we need to know more about the mechanism of the effect. Hence, the aim of the project is an in-depth study to elucidate the photochromic transition by a variety of thin film characterisation techniques. At the same time, we will further explore the properties of other oxyhydrides using combinatorial thin film techniques with sputtering and pulsed laser deposition.


You have a recently completed Master degree in Materials Science, Physical Chemistry or Condensed Matter Physics, preferably with a focus on optical and/or semiconducting properties. You have excellent academic qualifications and a passion for materials research. Strong experimental as well as communication skills and a pioneering mentality are essential for this project.

Conditions of employment

The TU Delft offers a customisable compensation package, a discount for health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. An International Children’s Centre offers child care and an international primary school. Dual Career Services offers support to accompanying partners. 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. The 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.
