Abstract
Bulk transparent glasses containing WO6-octahedra in various glass forming matrices have been prepared which exhibit ferroelectric-like, electrochromic and photochromic behavior. Cooperative phenomena of random electric dipoles in these systems were studied by the techniques of thermally stimulated depolarization currents. These systems exhibit dipole correlation at a critical concentration in the presence of an external electric field and at a specific temperature. A model was developed for a phase transition associated with such random “pseudo-spins” in an amorphous matrix. The photochromic and electrochromic behavior in these glasses are initiated by the double injection of electrons and ions.Keywords
