Instrument's Description

Fluorescence spectroscopy is among one of the powerful analytical probes being used extensively for analysis and characterization of compounds/materials in chemistry, materials science, physics, biotechnology, pharmaceuticals, environmental science, nanotechnology etc. A variety of light emitting diode (LED)/laser diode (LD) devices are employed as light source to generate ns/ps pulses over a wide spectral range. The pulse excites the sample from which the emission can be detected in UV-VIS to NIR range. The fluorescence decay kinetics along with the lifetime data usually provide an unambiguous identification of fluorescing material. The present fluorescence lifetime system is able to probe fast kinetic decay taking place in sub-nanosecond to fractions of second time domain. Besides, this method is also used to analyze the complex photochemical and energy transfer processes occurring in the excited state. Polarization accessory may be used to determine the fluorescence anisotropy.
