Double degree PhD fellowship in Chemistry
Start date is (expected to be) 1 December or as soon as possible thereafter, and no later than 31 December 2025.
The project
As a PhD candidate, you will explore the fundamental photoinduced processes in next-generation low-dimensional materials—including fully organic fluorescent nanoparticles,1-3 transition metal dichalcogenides,4-6 metal nanoclusters,7 metal halides, and quantum dots—using state-of-the-art ultrafast optical spectroscopy techniques. The research will focus on understanding charge carrier generation, transport, recombination dynamics, and energy transfer mechanisms. These insights will drive the development of highly efficient materials for advanced biomedical imaging applications, with potential extensions to light-emitting devices, photodetectors, and energy conversion technologies.
Our research project is highly interdisciplinary including collaborations with physicists, chemists, medical researchers, and biologists in the industry and at universities. Throughout the project, the candidate will be trained to be truly an interdisciplinary researcher in a creative and cross-disciplinary environment.
A period of 6 months of the project will be carried out in Institute of Semiconductor, Chinese Academy of Sciences, Beijing, China.
The PhD student will have the opportunity to pursue a double degree, subject to the rules and regulations of both the University of Copenhagen and the University of Chinese Academy of Sciences (UCAS). This arrangement offers a unique academic experience across two leading institutions. For more information about the double degree framework, please visit the (SDC) website.

Who are we looking for?
We are looking for a talented, highly motivated, and creative PhD candidate with a strong interest in low-dimensional optical materials and advanced optical spectroscopies. The ideal applicant will have a background in one or more of the following fields: Physics, Physical Chemistry, Materials Science, Nanoscience, Optical Spectroscopy, or Solid-State Physics. Experience with ultrafast spectroscopy, femtosecond pump-probe technique, photophysics, or optical characterization of nanomaterials is highly desirable. Familiarity with programming for instrument control and data analysis—using platforms such as Python, MATLAB, or LabVIEW—is considered a strong asset.
Our group and research- and what do we offer?
Light induced processes make the world bright and colourful. Furthermore, innovative ways of utilizing such processes have broad application possibilities in modern technology such as: bioimaging, solar cells, communication and photocatalysis.
Our group studies both the fundamental and applied aspects of the interactions between light and materials. In particular, we explore functions, underlying photophysics and photochemistry of fluorescent molecular materials and semiconductor nanomaterials.
We develop fluorescent materials and methods for bioimaging applications. We use femtosecond optical spectroscopy to reveal fundamental photophysical processes in these materials and provide a thorough understanding and guidance for developing new materials with improved performance. We carry our interdisciplinary research projects by collaborating with physicists, chemists, medical researchers, and biologists in the industry and at universities.
We offer a creative and exciting research atmosphere at the vibrant border between chemistry, physics and biomedicals. The PhD fellowship is given in accordance with Danish legislation and will typically run for 3 years. The salary is set accordingly to Danish Union Contracts which are competitive on an international scale.
