Spectroscopic material characterization

We have spectrophotometers, fluorescence spectrophotometers, and RAMAN spectrometers to use to investigate the optical, chemical, and molecular properties of materials.

Equipment in Joensuu:

• Edinburgh Instruments FLS-100 fluorescence spectrometer, light sources; Xenon lamp (450 W), 230 – 1000 nm, µF2 (60W) microsecond flashlamp: optical pulse 1,5µs to 2.5µs, repetition rate 0.1 Hz-100 Hz, and EPL-375 picosecond pulsed diode laser: 275 (±5) nm, measurement range 200 – 980 nm
• Bruker Vertex 70 FTIR spectrometer, spectral range 650 – 4000 1/cm
• Renishaw InVia Reflex confocal Raman microscope, excitation lasers 514 nm and 785 nm, measurement range 100 – 3200 1/cm
• Perkin Elmer Lambda 900 UV/VIS/NIR spectrophotometer, spectral range 200 – 3300 nm

Equipment in Tampere:

• Shimadzu UV-3600 spectrophotometer, range 180-3000 nm, including integrating sphere and specular reflection additions for non-transparent samples.
• Agilent Cary 60 spectrophotometer equipped with a customized sample chamber, which allows use of a temperature-controlled cuvette holder or a solid film holder, both of which can also be illuminated from the side or front-face during the measurement with an external light source.
• Edinburgh Instruments FLS-1000 fluorescence spectrophotometer, emission spectroscopy in the range 200-1600 nm, including phosphorescence steady state and decay (10 µs resolution) options and incubator for live cell studies.
• Bruker Invenio-R FTIR spectrometer, equipped with two detectors: room temperature DLaTGS (spectral range 8000-350 cm-1) and liquid nitrogen cooled photovoltaic MCT detector (spectral range 12 000-850 cm-1.) Transmission sample stage with temperature and humidity control, and ATR unit with temperature control up to 80 °C.
