Abstract A key strategy for minimizing our reliance on precious metals is to increase the fraction of surface atoms and improve the metal-support interface. In this work, we employ a solvent/ligand/counterion-free method to deposit copper in the atom

Singlet oxygen generation in porous silicon (PSi) was investigated by a magneto-optical experiment. Photoluminescence (PL) quenching due to an energy transfer (ET) process mediated by an exchange interaction was monitored in the spectral range 1.4–

The longitudinal acoustic velocity for 1 GHz waves propagating along the 100 direction in p++ porous silicon layers has been measured using an acoustic wave transmission technique. The velocities obtained are significantly higher than those previousl

An annular flow photochemical reactor illuminated by UV and green (524 nm) light emitting diodes (LEDs) was characterised by a chemical actinometer. Very high efficiency of absorption of photons, most likely promoted by the specific orientation of LE

Energy transfer from photo-excited excitons confined in silicon nanoparticles to oxygen dimers adsorbed on the nanoparticle surfaces is studied as a function of temperature and magnetic field. Quenching features in the nanoparticle photoluminescence

The red (1.8 eV) photoluminescence (PL) band often observed in Mg-doped GaN has been suggested to be due to a recombination process involving vacancy-related deep defects. To identify the defects concerned, optically-detected magnetic resonance (ODMR

We observe a systematic dependence of the g -values of magnesium acceptors on the photoluminescence energy that is used for the optical detection of magnetic resonance signals. This effect leads to a model which assumes that, in the magnesium accepto

We show that the spin-flip of electrons at neutral donors in a dilute magnetic semiconductor can be observed directly by means of optically-detected magnetic resonance (ODMR). Spectra obtained at 105 GHz for a bulk crystal of Cd 1-x Mn x Te with x= 0

Optically-detected magnetic resonance spectra from ZnO grown by molecular beam epitaxy and doped with nitrogen show signals due to electrons trapped at shallow donors and holes trapped at deep centres. The hole spectra have spin-Hamiltonian parameter

We have used spin-flip Raman scattering and photoluminescence to investigate ZnSe crystals doped with antimony, which is a potential p-type dopant. The experiments provide evidence for the existence of a shallow acceptor level at about 70 meV above t
