Photoluminescence Spectroscopy (4 K - 300 K)

The experimental setup includes a frequency doubled Ar+ laser with wavelength ranging from 244 nm to 514 nm, as well as a 325 nm He-Cd laser. Our temperature dependence experiment is facilitated by a Closed Cycle liquid helium cryostat which can cool samples down up to a temperature of 4K and a spectrograph fitted with UV-VIS and VIS-IR CCDs.
