Abstract

Based on [Ln(L)₃(H₂O)₂] (Ln = Nd, Yb or Er) complexes self-assembled from a trifluorinated acylpyrazole-type β-diketonate ligand HL ((Z)-3-methyl-1-phenyl-4-(2,2,2-trifluoro-1-hydroxyethylidene)-1H-pyrazol-5(4H)-one) and LnCl₃·6H₂O, a series of NIR luminescent PMMA-supported hybrid materials PMMA@[Ln(L)₃(H₂O)₂] are obtained from physical doping. The immobilization of the luminescent species via physical and chemical interactions within the polymeric PMMA matrix also acting as co-sensitizer, endows the enhanced NIR luminescent properties (Φ_em= 0.85-0.97%) in comparison to the individual Ln^{3 +}-β-diketonate complex (Φ_em= 0.53-0.79%) besides the improved thermal-stability properties.
