Labs in Regensburg

Laser Lab

The laser lab is home to the nonlinear optics setup. We have a fs-oscillator with about 0.6W power and 90fs pulse length with appropriate optics for linear, nonlinear and pump-probe experiments. A helium cryostat system with front access (for microscope objectives) and back access (for excitation beams) allows for micro-photoluminescence, nonlinear optical sample characterization and micro-electroluminescence experiments between 3.8K and about 450K.

Laser Lab 2

Microscopy Lab

This lab features a setup for single-molecule microscopy in confocal as well as wide-field mode.

Chemistry Lab

The chemistry lab is primarily used for sample preparation with wet-chemical methods. It also contains setups for absorption and fluorescence spectroscopy of fluid and solid film samples.

Surface Preparation Lab

The surface preparation lab is used for sample preparation and OLED preparation.

Labs in Utah

Single Molecule Spectroscopy Laser Lab

The single molecule spectroscopy laser lab is the primary lab of the group in Utah. All of the equipment in the lab was purchased and installed in the 2006/2007 academic year. The lab features a variety of state-of-the-art equipment assembled into a spectroscopic microscope that is centered around a broadly tunable Ti:Sapphire pulsed laser excitation source.

The featured equipment of the lab includes:

Electroluminescence Lab

A second lab was built to study the electroluminescence of polymer systems. Studies in this lab focus on material systems applicable to polymer based devices such as organic LEDs (OLEDs) and organic solar cells.

The electroluminescence lab contains:

Chemistry Lab

This lab is primarily used for sample and substrate preparation, however, the lab is also capable of accommodating more sophisticated chemistry.
