چکیده انگلیسی
A series of Tb-doped MgAl-NO3 layered double hydroxides (LDHs) with Mg2+/(Al3++Tb3+) molar ratios ranging from 1.0 to 4.0 were synthesized through co-precipitation method at room temperature. X-ray diffraction (XRD) results indicated that the crystallinity of all the Tb-doped samples presented a single phase corresponding to LDHs. SEM measurement suggested that all the samples have similar morphologies. Fluorescence spectra show strong green emissions at 490 and 544Â nm, ascribed to the 5D4â7F6 and 5D4â7F5 transition of Tb3+, respectively. This result revealed that the MgAl-NO3 LDH system was favorable for the green emissions of Tb3+ ions.
