Time evolution of (formula presented) thermal recovery has been investigated in detail by a piezoelectric photothermal method. Results showed a simple saturating behavior for (formula presented) and a sigmoid-function-like behavior for (formula presented) which were both quantitatively analyzed with an autocatalytic-reaction rate equation. The latter recovery mode indicates correlation between defects, for which recovery promotion by charge transfers from recovered to unrecovered (formula presented) defects can be suggested. A three-center-complex model (formula presented) is proposed for the microstructure of (formula presented).
