Abstract: The effect of magnetic field on luminescence intensity is generally expected to be rather weak. Contrary to this expectation, we report here an extraordinary strong intensity suppression (by two orders of magnitude) of the Er3+ S-4(3/2)-> I-4(15/2) green emission line in Er3+-doped nano-glass-ceramics by applying magnetic field up to 50 T. We argue that this effect arises from different site geometries and, consequently, strongly differing Judd-Ofelt intensities of transitions for the two Kramers doublets of the emitting S-4(3/2) multiplet.
