The luminescence properties of compounds 1-6 have been studied at different temperatures in the solid state and show the sensitization of the 4f-4f emission bands in the NIR range for compounds 1, 5 and 6. The molar magnetic susceptibility measurements of 1-6 in the 2-300 K temperature range indicate weak antiferromagnetic exchange for the isotropic Gd(III) compound 3. Furthermore, slow relaxation of the magnetization is found in complexes 5 and 6 with effective energy barriers of 9.5 cm 1 (0.1 T) and 22.7 cm 1 (0.15 T), respectively.27 p.application/pdfengcc-by-nc-nd (c) Elsevier Ltd, 2019http://creativecommons.org/licenses/by-nc-nd/3.0/esMagnetismeLuminescènciaMetalls de terres raresMagnetismLuminescenceRare earth metalsinfo:eu-repo/semantics/article6901832020-05-27info:eu-repo/semantics/openAccess
