The Quantaurus-Tau is a compact system for quickly and easily measuring the fluorescence lifetime of photoluminescent materials from sub-nanoseconds to the millisecond range, with single-photon-counting sensitivity. Samples in different forms―thin films, solids, powders, and solutions―can be analyzed. Liquid samples can be cooled down to -196 deg.C (77K) with liquid nitrogen.
Operation is simple. Just load the sample into the sample chamber. Then enter a few conditions on the measurement software to measure the fluorescence lifetime and photoluminescence (PL) spectrum. It only takes a minute to get analysis results for a typical measurement. The measurement software includes a variety of measurement and analysis functions such as multicomponent analysis and multisample data comparison.
The fluorescence spectrum obtained from an organic material or fluorescent probe is a vital parameter for controlling and evaluating the material functions and characteristics such as the peak wavelength and fluorescence intensity. However, a fluorescence spectrum usually shows time-integrated information, and so when the material contains multiple substances and reactive elements, their fluorescence spectrum can only be acquired as integrated information. An effective approach in such cases is to observe the light emission dynamics by making use of the time axis parameter. This is generally called fluorescence lifetime measurement, in which the time required for the substance excited by the pulsed light to return to its ground state is measured in the sub-nanosecond to millisecond region. This measurement allows obtaining more information such as multiple different fluorescence lifetimes even at the same wavelength and the percentage in which they are present within the material, etc.
