Abstract
The magnetic dipole interaction mechanism is shown to be important in a nonradiative energy transfer process of a lanthanide ion in a centrosymmetric environment. The concentration quenching of near-ultraviolet luminescence in Cs2NaTmCl6 may be explained by this mechanism, the calculated nonradiative transfer rate from the donor Tm3+ being 1.44×105s-1. The transfer rate decreases by a factor of 103 for transfer to the 7th nearest neighbours, compared with that to the 1 st nearest. However, the angular dependence of the transfer, and the different coordination numbers for nth nearest neighbours, lead to an increased transfer rate to 3rd nearest neighbours, compared with that to the 2nd nearest set; and to the 5th nearest neighbours compared with the 4th set
