The roles of electrons and holes in the photoexcitation of a samarium-doped titanium dioxide (TiO2:Sm) thin film were investigated with electrical measurement techniques. To determine these roles, the holes were selectively injected into TiO2:Sm by u

The design and use of a novel portable synchrotron end-station is described, that allows for the micro-imaging of X-ray absorption features of solids, via their luminescence emission. This mode of measurement is possible on most standard synchrotron

We have investigated the local atomic environment of the Ga atoms in an InxGa1−xN single quantum well structure using Optically Detected Extended X‐ray Absorption Fine Structure (OD‐EXAFS). A comparison of the OD‐EXAFS data with a theoretical

Rapid advances have recently been made at SRS Daresbury in optical-detection methods for both micro-imaging x-ray absorption spectroscopy (ODXAS, ODEXAFS), and in the development of volume-integrated synchrotron-laser pump-probe XAS methods (PP-ODXAS

We examine the near-IR light-matter interaction for graphene integrated cavity ring resonators based on silicon-on-insulator (SOI) race-track waveguides. Fitting of the cavity resonances from quasi-TE mode transmission spectra reveal the real part of

The mechanism of the temperature quenching of luminescence in samarium-doped titanium dioxide (TiO2:Sm) was investigated with electrical measurement techniques. Because electrical measurements are sensitive to charge dynamics, the indirect excitation

Anatase titanium dioxide (A-TiO2) with a wide band-gap energy of 3.2 eV can be used as a host semiconductor of rare-earth dopants for optical devices. However, the chemical activity of A-TiO2 strongly affects the luminescence properties of the device

Synchrotron?laser pump-probe (PP) luminescence measurements have been undertaken in hexagonal-phase boron nitride. For non-resonant excitation below the boron K-edge, the dynamics of the transients induced by the application of laser probes at 1.49,
