Light-Induced Electron Spin Resonance (LESR)... 

Reinacher and co-workers have performed light induced electron spin resonance (LESR) measurements [13] on GaN films and resolved a line at g = 1.997 which may be related to the deep donors observed in ODMR and EDMR measurements and discussed in the following sections. 

Photo-darkening and light induced electron spin resonance (ESR) are typical examples of reversible photo-induced effects. Photo darkening occurs when the material is irradiated with band gap photons...

Cmcial to photovoltaic apphcations, the first observation of a photoinduced charge transfer in double-cable polyfiillerenes was reported in 2000. Polymer 6, an electrochemically prepared polythiophene carrying fulleropyrrolidine moieties, was studied by means of different techniques, including steady-state photoexcited spectroscopy and light-induced electron spin resonance (Figure 8.5) [22, 23].
