We use the technique of fluorescence by two photon absorption to study some dyes that are important for applications in biological imaging. Some biological samples are autofluorescent, i.e. they have a high absorption cross ...

Radiative energy efficiencies of a multi-annular photocatalytic reactor were evaluated and analysed. The total quantum efficiency, defined as the ratio of the number of molecules of the pollutant reacted to the number of ...

In this work, we study the optical response of structures involving porous silicon and porous alumina in a multi-layered hybrid structure. We performed a rational design of the optimal sequence necessary to produce a high ...
