摘要：

EPR and optical spectra of LiNbO3: CU2+ showed that Cu2+ ions substitutionally take the position of Nb5+ ions. The spin-Hamiltonian parameters are determined to be gx = 2.076, gy = 2.106, gz = 2.381, Ax = 50.53 × 10-4 cm-1, Ay = 30.24 × 10-4 cm-1 and Az = 77.97 × 10-4 cm-1. One of the principal-axis systems for Cu2+ ions is given by Eulerian angles: θ1 = 51.7°, φ1 = 3.0°, and ψ1= -47.8° referred to the crystallographic ay'c system. The electronic state of Cu2+ in LiNbO3 is deduced from EPR and optical absorption data. © 1979.
