Energy transfer phenomena can play an important role in the development of luminescent materials. In this study, numerical simulations based on theoretical models of non-radiative energy transfer are compared to experimental results for Ce, Tb co-doped silica. Energy transfer from the donor (Ce) to the acceptor (Tb) resulted in a decrease in the Ce luminescence intensity and lifetime. The decrease...
The free 3‐quinolineboronic acid (3‐QBA) with the lowest (n–π*) excited singlet is non‐ or weakly fluorescent while protonated 3‐QBA has the lowest (π–π*) excited singlet state and is highly fluorescent. The hybridization of boronic atom or charge transfer from aromatic ring to boronic acid group plays a secondary role in affecting fluorescence intensity. Binding with carbohydrate at a proper acidity,...
