| Abstract: | The SrFCl:Eu2+ single crystal was grown by programmed cooling method, and its electron spin resonance (ESR) spectra were recorded. The g factors and ESR parameters were simulated with the Least-Square Fitting Method. The anisotropic g factors and related spin Hamiltonian parameters were reported. High-order forbbiden transition of Eu2+ in SrFCl:Eu2+ crystal were observed and assigned according to the calculation results. |
