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. With the PLII module adapted to a VERTEX series spectrometer, comfortable NIR PL measurements with highest sensitivity are readily available. Vacuum spectrometers such as the VERTEX 80v with dedicated vacuum PL module open the door to sophisticated and challenging applications like MIR PL or photomodulated reflectance.
