The influence of ionizing radiation on photo-thermo-stimulated exolectron emission (EE) spectra of gadolinium oxide (Gd2O3) nanoparticles and films was studied. During the irradiation, electrons can be excited from valence band and trapped in the localized states. The trapped electrons can be released from the localized states by thermal or photo stimulation. The released exoelectrons have low energies, in the order of several eV, and are emitted from a surface layer with thickness less than 10 nm. This makes it promising to use EE to detect radiation doses absorbed in several nanometers thick layers.
