Phys. 115, 243706 (2014); 10.1063/1.4885439 Ion-implantation induced nano distortion layer and its influence on nonlinear optical properties of ZnO single crystalsWe performed a comprehensive study of the EPR spectra of Cu 2þ ions embedded in single crystals of inverse spinel LiGa 5 O 8 and zinc tungstate ZnWO 4 . The EPR spectra were interpreted using a modified crystal field theory. It was found that the adiabatic potential of a Cu 2þ ion in LiGa 5 O 8 exhibits multiple minima, whereas the adiabatic potential of a Cu 2þ ion in ZnWO 4 has a single minimum. It was shown that the presence of low-symmetry distortions leads to the suppression of frustration and, ultimately, as in ZnWO 4 , to the formation of a global minimum of the adiabatic potential.

Optical detection of paramagnetic centres: From crystals to glass-ceramics

“…Magnetic resonance technique, particularly electron paramagnetic resonance (EPR) (or alternatively, electron spin resonance, ESR) spectroscopy is the powerful method for structural characterization of paramagnetic point defects in solids [1][2][3][4][5][6][7][8][9][10] which allows the determination (1) nature and valence of the impurity; (2) nature and number of ligands; (3) symmetry of the complex; (4) possible presence of nearby defects; (5) true metal-ligand distance and its dependence on pressure and temperature etc. The optically detected magnetic resonance (ODMR) allows the investigation of the structure of luminescence and colour centres [11].…”
