Abstract
The effect of cytosine on the fluorescence of Tb3+-doped CaAl LDH has been studied. The emission attributed to 5D4â7F5 transition of Tb3+ doped in CaAl-LDH gradually became stronger with increasing amount of cytosine incorporated in the Tb3+-doped CaAl-LDH. Meanwhile, the lifetime of the emission ascribed to 5D4â7F5 transition of Tb3+ gradually decreases with the increase in the amount of cytosine present in the Tb3+-doped CaAl-LDH. The mechanism of fluorescence enhancement based on the intermolecular energy transfer from cytosine to Tb3+ in the Tb3+-doped CaAl-LDH/Cyt. composites has been proposed.146
