Why europium acylpyrazolonates are bad phosphors: lessons learned from the study of ionic and polymer complexes MLnQ 4 , M = NEt 4 + , Ag +

Puntos clave

To explore why europium acylpyrazolonates are ineffective as phosphors despite their potential in luminescence.
Analyzed the luminescent properties of europium acylpyrazolonates in various complexes.
Compared their effectiveness with other lanthanide complexes.
Investigated the role of ionic and polymer environments in luminescence sensitivity.
European acylpyrazolonates did not perform well as phosphors in comparison to other lanthanide complexes.
Certain ligands effectively sensitized luminescence in Tb 3+, Dy 3+, and Sm 3+ ions.
Findings indicated limitations in the environment around europium ions affected luminescence negatively.

Resumen

Our series of works on acylpyrazolonates of lanthanides has shown that although these beta-diketonate ligands are effective in sensitizing the luminescence of Tb 3+ , Dy 3+ , Sm 3+ ions, and IR-emitting Yb 3+ ,...
