Abstract

Optical excitation of trivalent platinum (5d⁷, t⁶e) ions in lead titanate single crystals have been observed for the first time by electron paramagnetic resonance (EPR). The g and hyperfine coupling A tensors were found to be axial: g_∥=1.938, g_⊥=2.478, A_∥=0.0164 cm^-1, and A_⊥=0.0324 cm ^-1. Analysis of the EPR spectra using crystal field theory indicates that the Pt⁺³ ions are in tetragonally distorted (elongated) octahedral sites, strongly suggesting that they substitute for the central Ti⁺⁴ ions in the perovskite lattice.
