Abstract

A system is described, which allows photoluminescence measurements in the spectral region from 400 nm to 1.2 μm with a spatial resolution better than 1 μm and with an energy resolution of about 10 meV. The apparatus is based on a laser scan microscope. The luminescence excited by blue laser light (488nm) at arbitary points of the sample is detected by a photomultiplier positioned at the exit of a monochromator. Some results of investigations on GaAs / GaAlAs - heterostructures are presented.
