How to calculate the fluorescent decay rates (radiative and non-radiative) of two emitting species (flourophore) in solution i.e. two lifetimes ?

So I have the PL spectra and lifetime transients for a fluorophore in solution (Perylene based polymer in Chloroform) and so by fitting the transients I am able to extract 2 lifetimes one...

Anyone familiar with correlation coefficient of a block matrix?

My question is related to the computation of correlation coefficient of a block covariance matrix. The correlation coefficient can be computed as: r = cov(X,Y)/std(X) std(Y) But if I have a block...

How can I explain that the residual stress can shift some xrd peaks in one direction, and other peaks in the opposite direction for the same sample?

This is may be due to the need to balance stress at grain boundaries, and satisfy constraints on the strain tensor (for example a tensile stress along one direction must be balanced by a...

How the Ground Plane implantation is performed without damaging (and w/o varying the undoped nature) the top Si (8-10 nm) in FDSOI technology ?

It is a general practice to introduce Ground Plane in FDSOI devices under the BoX. The Ground Planes are introduced by Ion Implantation through Top Si layer and Buried Oxide. I wanted to know that...
