Abstract
Persistent spectral hole burning (PSHB) in the transition and the electron excitation in the transition of doped in glasses were studied from the measurements of hole burning efficiency and the refilling of the burnt hole. The PSHB at low temperature is attributed to the optically activated rearrangement of OH bonds surrounding ions. On the other hand, the PSHB at high temperature is attributed to one-step electron tunneling in the excitation state. The barrier heights for hole filling corresponding to the two mechanisms were determined to be ∼0.27 and ∼0.90 eV, respectively. Thermal depth of the trap that captures electrons by two-step ionization via the state was determined to be ∼0.35 eV below the conduction band. A model was proposed for describing the PSHB and electron excitation of doped in glasses. In addition, the dependence of hole burning efficiency on the concentration, temperature, and burning wavelength was also studied.
