Due to its wide band gap and high carrier mobility, ZnO is, among other transparent conductive oxides, an attractive material for light-harvesting optoelectronic applications. Its functional efficiency, however, is strongly affected by defect-related in-gap states that open up extrinsic decay channels modify relaxation timescales. As a consequence, almost every sample behaves differently, leading irreproducible or even contradicting observations. Here, complementary set of time-resolved...
The realization of the potential hybrid inorganic organic systems requires an understanding coupling between constituents: its nature and strength. observation optical transitions in monolayer WS 2 /terrylene is reported. first‐principle calculations, linear optical, transient absorption spectroscopy are employed to investigate spectrum hybrid, which exhibits a new transition that does not appear constituents’ spectra. calculations indicate type II level alignment, with highest occupied...

Photocatalytic water-splitting provides a way to store solar energy as hydrogen gas, and hence, is an attractive alternative energy-intensive electrolysis of water. Microporous polymer networks are interesting class heterogeneous photocatalysts due the chemical modularity their optically active backbone guest-accessible pore-structure. action depends on efficient separation photoexcited electron-hole pairs, recently, it was discovered that this can be improved by incorporation donor-acceptor...
Photocatalytic water-splitting provides a carbon-neutral alternative to energy-intensive electrolysis store solar energy in the form of hydrogen. Microporous polymer networks are an intriguing platform for design increasingly more performant photocatalysts due their chemical modularity and band-gap tuning potential. Their efficacy depends on efficient separation photoexcited electron-hole pairs. Conventionally, this is achieved by deposition expensive platinum as co-catalyst. More recently,...
