Service description

The service of photoluminescence allows measurements of the spectral distribution of the optical emission in semiconductors, which yield information on the material properties associated with the electronic structure in a simple and nondestructive way. In addition of being able to determine the band gap of the material and use its composition dependence in alloys to determine their composition, the technique is particularly sensitive for the identification of impurities in the crystalline lattice. The laboratory has available a high-resolution Jobin-Yvon FHR1000 spectrometer equipped with a Si CCD detector covering the spectral range between 350 and 850 nm and an InGaAs detector that covers the spectral range between 850 and 1600 nm. As excitation sources, a He-Cd laser (325 nm) and a Nd:YAG (532 nm)
