Tunable electron and hole injection channels at plasmonic Al-TiO2 interfaces

Metallic nanostructures can strongly absorb light through their plasmon excitations, whose nonradiative decay generates hot electron-hole pairs. When the metallic nanostructure is interfaced with a semiconductor, the spatial separation of...

Substitution effect on the nonradiative decay and trans → cis photoisomerization route: a guideline to develop efficient cinnamate-based sunscreens

Para-substituted cinnamates are promising sunscreen reagents. They undergo efficient multistep nonradiative decay via the 1nπ* (and/or 3nπ*) and 3ππ* states and finally trans → cis photoisomerization. Para-substitution stabilizes π orbitals and enhances the photoisomerization.

Donor–acceptor–acceptor-type near-infrared fluorophores that contain dithienophosphole oxide and boryl groups: Effect of the boryl group on the nonradiative decay

he use of donor–π–acceptor (D–π–A) skeletons is an effective strategy for the design of fluorophores with red-shifted emission. In particular, the use of amino and boryl moieties as the electron-donating...
