Theoretical study of the mechanisms of activation/deactivation of luminescence in a UiO-66 type sensor modified with Ln3+ (Eu and Tb) as dopant ions

In this report, a quantum chemical theoretical protocol was used to elucidate the detection principle of the turn-on luminescence mechanism in a modified MOF labeled as Ln 3+ @UiO-66-(COOH) 2 (Ln 3+ = Eu 3+ or Tb 3+ ).
