Description

Spectroscopy lab occupies one half of a room and contains apparatus for recording steady-state absorption and emission spectra. Absorption spectrometer Lamda 1050 (Perkin Elmer) can measure absorption spectra in high resolution from UV to IR (~200-1600 nm), operating in dual beam mode (sample and reference) and can be equipped with integrating sphere. Emission spectrometer Fluorolog-3 from Horiba, coupled with TRIAX spectrometer can measure both excitation and emission spectra in wide range of wavelengths due to several available detectors (PD, CCD and InGaAs PD for IR detection).

Equipment and resources

Absorption spectrometer Lamda 1050 (Perkin Elmer) can measure absorption spectra in high resolution from UV to IR (~200-1600 nm) from very diluted samples up to very high OD (saturates around OD 8). Operation in dual beam mode (sample and reference) assures that correct background can be subtracted at the same time as the sample is measured. Both liquid and solid samples (films) can be measured. The integrating sphere is particularly useful for high-scattering samples. Emission spectrometer Fluorolog-3 from Horiba, coupled with TRIAX spectrometer can measure both excitation and emission spectra in wide range of wavelengths due to several available detectors. PD offering high sensitivity over broad range of wavelengths, CCD for detecting large spectra region at a time and InGaAs PD for detection of IR photons. Both CCD and InGaAs need to be cooled by liquid nitrogen for noise suppression.
