Electron Spin Relaxation of Tb and Tm Ions.

Electron spin relaxation times T and T of Tb and Tm in 1:1 water:ethanol and of Tb doped (2%) in crystalline La(oxalate) decahydrate were measured between about 4.2 and 10 K. Both cations are non-Kramers ions and have J = 6 ground states.

Structural and spectroscopic investigations on the quenching free luminescence of europium oxalate nanocrystals.

The structural features leading to the intense quenching free luminescence exhibited by europium oxalate nanocrystals, poly[[hexaaquatri-μ-oxalato-dieuropium] 4.34-hydrate], {[Eu(CO)(HO)]·4.34HO}, is the focal point of this report.
