Chemistry and properties of Ln(III) Oxidation state +III is most common Hard acids Prefer hard donor atoms O>N>>P,S Large cations Large coordination numbers –Core 4f electrons –Omnidirectional/ionic bonding –Coordination numbers dictated by steric bulk of ligands Similar ionic radii Magnetism Light emission due to f-f transitions –Core 4f orbitals –Characteristic emission colors –Sharp emission bands –f-f transitions forbidden by selection rules CN 6: r ion Ce 3+ =115.0 pm r ion Lu 3+ =100.1 pm

Antenna effect

Emission colors Eu(III) Tb(III) Tm(III) 5 D 0 → 7 F 2 ~615 nm 5 D 4 → 7 F 5 ~545 nm 1 G 4 → 3 H 6 ~480 nm
