Transformation of Nd3+ Centers in Y2SiO5 Crystals during Heat Treatment in a Reducing Atmosphere and Gamma Irradiation

Inorganic Materials Aims and scope

Abstract—

We have studied absorption spectra of Y2SiO5:Nd crystals after gamma irradiation and heat treatment under reducing conditions. The results demonstrate that, during gamma irradiation or heat treatment of the crystals, the generation of oxygen vacancies in the vicinity of Nd3+ ions coordinated to seven oxygens (Nd1 centers) changes their oxygen coordination to six (Nd2 centers), that is, causes a partial transition of Nd1 to Nd2 centers.
