Energy transfer

Energy transfer is the process by which energy is relocated from one system to another, for example, through the transfer of heat, work or mass transfer. In chemistry, the affect of atomic or molecular composition on energy transfer is studied, examples of which include energy transfer through molecular collisions or through fluorescence resonance energy transfer.

    Homo Förster resonance energy transfer is a key process in natural photosynthesis, among other systems, but model systems for this process are complicated by emission from both donor and acceptor. Here desymmetrisation of identical chromophores within DNA allows quantitative study of the distance and orientation dependence of homo-FRET.

    Exciton/recombination events in semiconductor quantum dots are highly dependent on surface coordination environments and these processes are well studied. Here, conversely, the authors use sum-frequency generation spectroscopy to probe the effect of the quantum dot on the vibrational structure of the ligands.

    2D electronic spectroscopy enables a spatially-averaged view of the electronic structure of a heterogeneous system. Here, the authors extend it to sub-micron resolution and ~106 times better sensitivity, to resolve spatially varying excitonic structure in a heterogeneous mixture of photosynthetic cells.

    Steric effects in a fundamental energy-transfer reaction at collision energies from over 1,000 K down to 20 mK have now been studied. At high energies a pronounced dependence of the reactivity on the reactant orientation is observed, but this effect is not present at the lowest energies because of dynamic reorientation.

    Controlling ferroelectric polarization is conventionally achieved by applying electric fields, mechanical force or similar. Here reversible switching of the bulk polarization of a BiFeO3 thin film is demonstrated by pattering aqueous solution on to the surface enabling large-scale switching.

    Optimizing luminescence from quantum dots benefits various optoelectronic and photovoltaic applications. Here the authors drive high-efficiency, tunable upconversion luminescence in perovskite quantum dots by energy transfer from lanthanide-doped nanoparticles excited by near-infrared light, to produce full-color emission with low driving power.
