SHnoSw2 ehvaevre, the efficiencies of single phase semiconductors are often limited by charge recombination11,12, and in some cases by large band gaps. While UV-light corresponds to less than 5% of the solar spectrum13, materials may be func- tionalized to red-shift their solar light ...
We have elucidated the UV photochemistry of L-cystine upon 267-nm excitation by employing femtosecond X-ray absorption spectroscopy at the sulfur K-edge. Solvent-mediated primary geminate recombination occurs effectively via a vibrationally highly excited state, which can lead to perthiyl radical format...

Figure 5. Triplet state decay of some aromatic molecules in solution. The long life of triplet states (typically in the millisecond/microsecond range for organic molecules in solution), which results from the spin-forbidden nature of their transition to the ground state, makes them responsible for...
We also have demonstrated that a controllable coassembling of dye molecules and electrolyte components on semiconducting nanocrystals can reduce surface states and inhibit charge recombination synchronously. 展开 关键词: THIOPHENE EFFICIENT ELECTROLYTES DESIGN FURAN ...

by organic carbon. This light absorbing OA is known as brown carbon (BrC). These compounds absorb light in near-UV and visible spectral regions, which also influences atmospheric photochemical processes and leads to the formation of secondary organic aerosol (SOA)2,3. The light absorption ...
Surface enhanced absorption is a plasmonic effect parenting to surface enhanced fluorescence and Raman scattering, and it was clearly reported to occur in the infrared region of the spectrum of light. In this paper, we unambiguously show that it also occ
