ESR and spin-lattice relaxation of Nd3+ in silicates of various structures

Abstract

ESR studies have been made on Nd3+ in certain orthosilicate and pyrosilicate single crystals. It is found that Nd3+ ions produce a type of activator center, and the principal values of the chief factors have been measured. The ESR spectra are compared with structural data on the crystals. The spin-lattice relaxation gives the positions of the nearest excited Stark level of Nd3+ in the silicates. © 1983 Plenum Publishing Corporation.
