Title: Local Structure Determination of Al_2O_3∶Ni~(2+) Crystals from the Optical Spectra and EPR Spectra
Abstract: In this work,according to the complete diagonalization procedure(CDP) and the Semi-SCF d-orbit model and the point charge model proposed by Zhao,assuming the structure symmetry of crystals haven't been destroyed,the unknown and changed crystal local structure parameter of Al_2O_3∶Ni~(2+) can be determined from the optical spectra and electron paramagnetic resonance(EPR) spectra,and the relationship between the optical spectra, EPR spectra and the crystal local structure parameters is set up.Calculation indicates that the optical spectra,EPR spectra and magnetic susceptibility,of Al_2O_3∶Ni~(2+) crystals can be interpreted uniformly.The theoretical results are in good agreement with experimental data.
