External Electromagnetic Field Induced Electronic Structures and Novel Optical Functions of Rare-Earth-Ion-Doped Glasses

摘要

We researched the realization of novel optical functions of glass by combining an external electromagnetic field induced electronic structure and rare-earth-ions. We reviewed the phenomena, mechanisms, and the applications of photostimulated luminescence induced by X-ray, long-lasting phosphorescence by ultra-violet light, space-selective manipulation of the valence state of rare-earthion, and the formation of rare-earth-ion-doped optical waveguide for light amplification by a focused infrared femtosecond laser. The proposed concept will lead to a new possibility in the realization of novel optical functions for rare-earth-ion-doped glasses.
