Structure and photoluminescence of a new binary Mg/Tb layered double hydroxide

A series of binary Mg/Tb layered double hydroxides (Mg/Tb-LDHs) with different Mg2 +/Tb3 + molar ratios have been synthesized in ammonia water media by hydrothermal method. The composition, structure, and photoluminescent property of samples have been studies. All the Mg/Tb-LDHs samples have similar structure, and exhibited good photoluminescence. Moreover, the strongest emissions were observable to be at Mg2 +/Tb3 + molar ratio of 3.0. This new binary Mg/Tb-LDH would be potential application as luminescent materials.172
