Zusammenfassung
A zero-field optically detected magnetic resonance (ODMR) signal has been observed at T = 1.5 K for [0s(bpy)₃J²⁺ doped into a matrix of single-crystal [Ru(bpy)₃J(PF₆)₂. In the investigated microwave frequency range of 2 GHz <= ν <= 6 GHz, a resonance is seen at 4.56 GHz (~= 0.152 cm⁻¹) corresponding to the lowest excited state of the dopant. Thus, it is shown that this state is split into ...

A zero-field optically detected magnetic resonance (ODMR) signal has been observed at T = 1.5 K for [0s(bpy)₃J²⁺ doped into a matrix of single-crystal [Ru(bpy)₃J(PF₆)₂. In the investigated microwave frequency range of 2 GHz <= ν <= 6 GHz, a resonance is seen at 4.56 GHz (~= 0.152 cm⁻¹) corresponding to the lowest excited state of the dopant. Thus, it is shown that this state is split into sublevels. From the occurrence of the ODMR signal, it follows that the relaxation rates between the sublevels are smaller than other deactivation rates.
