CNMS Fluorometer and Luminescence System
Steady state and time-resolved luminescence spectrometer is used to study the emission properties of materials. The JY Horiba fluorometer uses monochromated light to enable excitation between 250 and 800 nm, and measures luminescence (phosphorescence, electro-luminescence, fluorescence) of materials (solids, powders, liquids) and devices (PV, LED and electrochemical) between 250 and 1800 nm, luminescence decay and fluorescence anisotropy ( typical application- study of protein-peptide or protein-nucleic acid interactions).
Specifications/Capabilities/Extras
System allows automated experiment, scanning a range of excitation wavelength while measuring fluorescence spectra, and generating 3D excitation-emission maps. This system is equipped with additional light sources, tunable (266-1064 nm) nanosecond excitation, to enable measurements of luminescence lifetime. Build in polarizers in excitation and emission path allows measurement of fluorescence anisotropy/fluorescence polarization allows measurements of molecular rotation.
