Lifetime Density Analysis
- Details
- Written by Chavdar Slavov
The great number of spatial, energetic and temporal degrees of freedom of the studied molecule ensembles and their matrix produces a continuous distribution of individual exponential decays. In this respect, the approximation of the data profile by a discrete set of exponentials (GLA and GTA) must be interpreted as a curve parameterization, concealing potential contribution of a larger number of underlying decays. Within lifetime density analysis (LDA) a quasi-continuous sum-of-exponents function is used to perform model-independent analysis of the experimental data. The methods yields a lifetime density/distribution map (LDM) which gives a comprehensive overview of the kinetics.
