Photoluminescence (PL) and electroluminescence (EL) measurements are standard techniques for evaluation of the crystallinity, functionality and luminescent mechanism of semiconductors. For these samples, near-field optical microscopy is the only effective method for characterization of the composition and distribution of luminescent centers on the nanometer scale.

In combination with a superconductive magnetic field, luminescent spectral measurements of the sample surface can be accomplished with nano-scale spatial resolution while applying temperatures as low as 7K and magnetic fields as high as 4 Tesla.
