Abstract

Optical excitation of trivalent platinum (5d 7 , t 6 e) 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.
