Sensitized luminescence from lanthanides in d–f bimetallic complexes

Study on preparation and characterization of MOF based lanthanide doped luminescent coordination polymers

“…This problem is overcome by using a strongly absorbing chromophore to sensitize Ln(III) emission in a process known as the antenna effect (or sensitization). One common method is to use organic ligands in coordination compounds and complexes as antenna [25]. In addition, the luminescent intensity of lanthanide coordination complexes increased remarkably when doping with the transition metal ions (such as Zn 2þ ) [13].…”

Syntheses, structures and photophysical properties of heteronuclear Zn–Ln coordination complexes

“…Piguet et al [25] report CrLn and Ru-Ln complexes, which make use of the lower energy of Cr( 2 E) and Ru( 3 MLCT) states as energy donors to enhance the luminescence of Ln 3 þ ion. So the d-f heteronuclear complexes have attracted extensive interest in the sensitization of the luminescent Ln 3 þ ion [26]. In addition, some d-f heteronuclear complexes also exhibit magnetic properties.…”

Sm(III)‐Bi(III) Heterometallic Complexes with Aminopolycarboxylate Ligand: Structure, Thermal Stability and Spectral Property

“…Except for organic ligands as "antennas" to sensitize rare earth ions, some metal ions involved in heterometallic complexes can be as sensitizers on the luminescence of Ln(III). 11,12 It is well-known that trivalent bismuth cation in inorganic compounds or hosts commonly exhibits interesting luminescence properties originating from the excitation and relaxation of its 6s 2 inert lone pair electrons, and it can be used as not only an activator but also a sensitizer of luminescence of Ln(III) in inorganic compounds or inorganic materials. [13][14][15] Polyaminopolycarboxylate is a sort of flexible and stable ligand, and can be bridged between metals ions to form heterometallic complex through bridged carboxylates.…”
