Photoluminescence (PL) spectroscopy is an important semiconductor analysis technique in material sciences as well as for research and development of optoelectronic devices such as lasers, LEDs or sensors. PL is a valuable tool to study the band structure, exciton features, sample quality or phonon modes of hetero structures (e.g. quantum wells) or bulk samples. Based on decades of experience Bruker offers powerful PL solutions with the VERTEX FT-IR research spectrometer series forming the backbone.
