The rate coefficients of the radiative and non-radiative deactivations, k r and k nr , can be obtained from the fluorescence lifetime and fluorescence quantum yield, using the set of Equations (4) and (5): (4) 1 τ F = k F = k r + k n r (5) Φ F = k r k r + k n r As shown in Table 2 , the values of k r fall all in the range of 1.5–2.0 × 10 8 s −1 and do not show a clear trend with the viscosity.
Such perovskite-like oxides demonstrate relatively high chemical reactivity in ion exchange [ 7 , 8 ], intercalation [ 9 , 10 ], and exfoliation processes [ 11 , 12 , 13 , 14 ]; some of them have practically significant photocatalytic [ 5 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ], electrophysical [ 23 , 24 ], and luminescent [ 25 ] properties.

Kinetic Evaluation The analysis of the plots 1/c = f(t) for both the oxidation of BAL and LOM while using ACVA and H 2 O 2 demonstrated a highly significant correlation which confirmed that the oxidation process followed the kinetics of second order reaction ( Figure 10 , Figure 11 and Figure 12 ).
