Spectroscopic Characterization of Mn:YAIO/sub 3/, Material for Holographic Recording and Optical Data Storage

Abstract

In work [1] we have studied photoinduced absorption, associated with it refraction index change, and holographic grating recording in Mn doped yttrium orthoaluminate (Mn:YAlO3). We have shown Mn:YAlO3 to be a promising material for optical storage and holography. In the present work, we spectroscopically investigate Mn ions in different valence states as well as transitions between different valence states responsible for photoinduced coloration of Mn:YAlO3.
