Our Techniques
Room Temperature & Cryogenic Photoluminescence and Raman Spectroscopy Setups
In the Nano-spectroscopy Lab we do spectroscopy at the nanoscale on nanostructures. We are expert in the design and realization of customized advanced optical spectroscopy setups for photoluminescence, absorption, and Raman measurements performed in a spatially-resolved manner on single nanostructures.
Home built experimental Setup
We have both room temperature and cryogenic (closed-cycle cryo-free cryostat) setups.
We apply these techniques under different experimental conditions (varying excitation power density, sample temperature, light polarization, magnetic fields etc).

Tunable Excitation Light
We have three extra narrow-band continuous wave lasers one pulsed light source with tunable wavelength (450-1100 nm) and tunable repetition rate. We have spectrometers and detectors to detect signal from 450 nm to 2100 nm.
Second-order autocorrelation Setup
We can perform also second-order autocorrelation measurements (g2) and time resolved photoluminescence spectroscopy.
Micromanipulation Setup
We are able to work at the edge of the light diffraction limit or to beat it with several techniques, such as beam shaping or coupling to AFM tips (near-field optical microscopy), achieving a 50-100 nm spatial resolution.
Micromanipulators equipped with Metallic Tips for fine NW placement
We are specialized in the micro-manipulation of single nanostructures and in the integration of nanostructures into new devices.
