Nanooptics Group - Faculty for Chemistry and Pharmacy

General theme: Development and application of new techniques for optical imaging and spectroscopy with high spatial and temporal resolution.

Near-field optical microscopy and spectroscopy
The strongly enhanced optical fields in the vicinity of a sharp metal tip are used to for optical microscopy and spectroscopy with nanometer-scale resolution. more...

Pervoskite thin films for optoelectronic applications
We study the optoelectronic and structural properties of perovskite thin films employing a set of complementary techniques. more...

Time-resolved microscopy
We use time-resolved photoluminescence and pump-probe microscopy to observe the excited state energies and dynamics in 1D and 2D materials. more...

Ultrafast Nanooptics
Ultrafast nanooptics combines the concepts and tools of ultrafast spectrocopies, such as coherent control of excited states, with those of near-field optics. We aim at the spatial-temporal control of optical near-fields on femtosecond time and nanometer length scales. more...

Fourier-space imaging
We apply Fourier-space imaging to explore the radiation pattern of molecular systems, optical nanoantennas as well as 1D and 2D materials. more...

Single-walled carbon nanotubes (SWCNT)
Carbon nanotubes are cylinders made of carbon atoms. They are typically between 0.5 and 2 nm in diameter, but several microns in length. Because of their unique mechanical and electrical properties, carbon nanotubes are considered for various technological applications, e.g. integrated circuits, nanotube actuators and optoelectronic devices. more...
