DAS6 Decay Analysis Software

HORIBA Scientific decay analysis software recovers kinetic information (such as fluorescence lifetime and rotational correlation times) from luminescence decay data by fitting the raw decay data to one of a selection of kinetic models. Features such as shift iteration and reconvolution of instrument response function (IRF, or "lamp" profile) allow accurate recovery of multiple decay components even when the decay data is grossly distorted by the IRF.

DAS6 is designed to streamline the analysis of time-domain luminescence data, while still allowing for fine-tuning of parameters where necessary.  Analysis modules include reconvolution analysis of multi-exponential models plus analysis of more specialised fluorescence decay processes as detailed below.

Multi-Exponential

Analysis for up to 5 exponentials.

Batch Exponential

Batch mode supports datasets containing up to 10,000 decays and is ideal for applications where large amounts of lifetime data are generated e.g. lifetime imaging and reaction monitoring.  It features full reconvolution with up to five exponentials and shift iteration.

Global Exponential

Perform global analyses of up to 5 exponential components and 100 decay curves.

Distribution

Two methods are available for performing lifetime distribution analysis.  The first method employs a “Top Hat” distribution function which allows a single lifetime distribution to be fitted in conjunction with an additional discrete lifetime.  The second method is an optional module which will perform a Non-Extensive Decay distribution which allows up to five lifetime distributions to be modelled.

Exponential Series

Exponential series analysis of up to 30 terms.  This allows parameterisation of otherwise difficult data.

Foerster Energy Transfer

2D and 3D Foerster type energy transfer with an optional exponential component.

Yokoto-Tanimoto Energy Transfer

Yokoto-Tanimoto energy transfer taking into account diffusion with an optional exponential component.

Micellar quenching

Micellar quenching kinetics can help determine the surfactant aggregation number.

Exciplex

Exciplex analysis follows formation of an excited state species.

Anisotropy analysis

Impulse reconvolution of up to 2 correlation times and 5 fluorescence decay components.  Each model parameter, including shift, can be fixed at a pre-determined value or optimised as part of the parameter fitting.  The use of reconvolution allows accurate determination of decay times and rotational correlation times even when the observed decay is grossly distorted by the duration of the excitation pulse.

 

DataStation TCSPC Acquisition Software

DataStation is the latest measurement environment for time-domain fluorescence and is supplied with all HORIBA Scientific lifetime systems.

Lifetime systems are made up of various modules and components, including pulsed light sources, PMTs, monochromators, motorized polarizers, focusing optics, MCAs etc. DataStation integrates the control of all these components into one intuitive, mouse-driven Windows environment.

Lifetime systems can perform a variety of measurement functions, such as fluorescence decay measurement, phosphorescence decay measurement, time-resolved anisotropy measurements, steady-state spectra, time-resolved emission scan (TRES), temperature scans and more. These measurements are now routine using DataStation. Measurement templates are provided to quickly set up the instrument for the required measurement, and automated data acquisition is performed using computer controlled components.

Acquired data can be saved in a variety of formats including the .das format, HORIBA Jobin Yvon IBH v4.2, and ASCII, printed to your Windows printer, exported or copied to the clipboard for manipulation using a third-party application.

DataStation can be purchased separately for use on non-HORIBA Scientific systems, and we are happy to add custom functionality and interfacing (e.g. to additional monochromator types, motorized polarizer holders etc).

The DataStation software comes into its own when combined with a FluoroHub.

Samples can be valuable. Either you don’t want to waste them, or you may not have very much starting material. Biological proteins and enzymes, for example, are often obtained in small volumes and may be expensive.
Nanophotonics with Fluorescence Instruments
Nanophotonics with Fluorescence Instruments
HORIBA Jobin Yvon’s spectrofluorometers have many applications in nanophotonics research: single-walled carbon nanotubes (SWNTs), quantum dots (QDs), and organic light-emitting diodes (OLEDs). Quantum confinement affects nanomaterials’ photoluminescence: when the semiconducting nanoparticle is smaller than the bulk material’s Bohrexciton radius, the bandgap energy is inversely proportional to the nanoparticle size.
Recording Fluorescence Quantum Yields

When a fluorophore absorbs a photon of light, an energetically excited state is formed. The fate of this species is varied, depending upon the exact nature of the fluorophore and its surroundings, but the end result is deactivation (loss of energy) and return to the ground state.
