Laboratory of photoluminescence spectroscopy

Low temperature photoluminescence (PL) spectroscopy enables efficient investigation of the electronic structure of semiconductor materials and structures.

PL spectrometer in IPE consists of a Sumitomo optical He closed cycle cryostat coupled with THR 1000 monochromator (Jobin-Yvon) and FTIR spectrometer Nicolet 5700.

The PL setup enables sensitive and high resolution measurements in the following spectral (300-9000 nm) and temperature (3.5-300 K) ranges.
