文摘
The effect of CH and CD quenching on the luminescence lifetime of ErP>3+, Nd3+, and Yb3+ in the Cs[Ln(HFA)4] system has been quantified, and we have shown that for Er3+ ions the quenching is dominated bythe nearest neighbor CH oscillators, whereas for Nd3+ ions the roles of more distant CH oscillators andnearest neighbor CD oscillators are important.
