Abstract

We measured the spectral dependency of persistent photoconductivity (PPC) in GdBa₂Cu₃O_6.3 from the near infrared to the ultraviolet energy range. For a photon energy of 4.1 eV there is a strong enhancement in the excitation efficiency. Photons with this energy create electron-hole pairs close to oxygen vacancies in the Cu-O chain layers. This increases the probability of the excited electron to get trapped at an oxygen vacancy, and thus leads to a strong enhancement of the excitation efficiency of the PPC.
