Abstract :
Large reversible photochromic changes were observed in SrTiO3double doped with Mo and either Fe or Ni. The photochromic absorption is induced by irradiation in the vicinity of 4000 Å and decays thermally in minutes or can be bleached to its original state by long wavelength radiation. A model is presented in which a charge is transferred between the Fe and Mo ions via the conduction or valence bands. Optical absorption, heat treatment, and EPR data are presented, which support the model.
