Description
Summary:Electron and nuclear spins in solids, coherently coupled to photons, provide promising resources for quantum information processing and sensing. Obtaining information about short-lived excited states is critical for realizing ultrafast all-optical spin control methods. After a brief review of early magnetic resonance studies of excited states, the following representative examples of the use of magnetic resonance spectroscopy to study excited states in wide-gap materials, semiconductors and nanostructures based on them will be considered: (1) optically detected magnetic resonance (ODMR), electron spin echo, electron-nuclear double resonance in the excited state on the example of self-trapped excitons in ionic-covalent silver halide crystals and nanocrystals, (2) ODMR and level anticrossing (LAC) spectroscopy of localized heavy-hole excitons in semiconductor quantum wells and superlattices, (3) LAC and ODMR in excited states of spin centers in diamond and silicon carbide, (4) the use of LAC and cross-relaxation for all-optical sensing with submicron spatial resolution.
