Quenching of IR luminescence of erbium, neodymium, and ytterbium beta-diketonate complexes by ligand C-H and C-D bonds
The effect of CH and CD quenching on the luminescence lifetime of Er3+, Nd3+, and Yb3+ in theCs [Ln-(HFA)(4)] system has been quantified, and we have shown that for Er3+ ions the quenching is dominated by the nearest neighbor CH oscillators, whereas for Nd3+ ions the roles of more distant CH oscillators and nearest neighbor CD oscillators are important.
