Our Spectroscopy laboratory is equipped with an FT-IR spectrometer with various attachments (including ATR) and a microscope, a UV-VIS-NIR spectrophotometer, a fluorescence spectrometer, and a spectrometer for dynamic light scattering (DLS).

  • Spectroscopic measurements
  • Hands-on education in the use and application to assess spectral properties of solutions, thin films and solids
  • Bench and fume hood space to prepare the samples
  • Collaborative research opportunities
  • Data interpretations and recommendations
  • Full-service and self-service options
  • Support in academic courses
  • Specialized workshops
  • Agilent (Cary) UV-Vis-NIR:  Equipped with VASRA or Variable Angle Specular Reflectance Accessory that is used with thin films at angles from 20 to 70 degrees; Praying Mantis diffuse reflection analysis of solids and powders.
  • Edinburgh FS5 spectrofluorometer:
    • Light source: 150 W xenon lamp
    • Excitation monochromator: 200-1000 nm; Emission monochromator: 200-1000 nm
    • Reference, Transmission and Emission detectors (230-870 nm spectral range for emission)
    • Fluorescence lifetime capability (TCSPC – Time Correlated Single Photon Counting)
    • TCSPC sources: EPLED 320nm, 365nm, 450nm, and 650nm LEDs, and EPL 510nm pulsed diode laser
    • Temperature controlled sample holder and solid sample holder
    • Integrating sphere for quantum yield measurements
  • Malvern Zetasizer Nano ZS:  With 633nm ‘red’ laser- for size measurement of particles and molecules (e.g. proteins) dispersed in a liquid (using dynamic light scattering, DLS); zeta-potential of colloids and nano particles for predicting dispersion stability (using electrophoretic light scattering); and the measurement of microrheology of protein and polymer solutions. The high performance of this instrument also enables the measurement of molecular weight of macromolecules.
  • Nicolet iS-50 FT-IR spectrometer:  With ATR-ZnSe for thin films, powders and liquids; Harrick Grazing Angle Reflectance Accessory for thin films on metal or semiconductor substrates; Gemini Diffuse Reflectance Accessory for non-reflecting powder materials.
