Structure and Luminescence Characteristics of Terbium Hydroxide Nanosheets Doped with Eu³⁺

Abstract:

Eu³⁺ doped terbium hydroxide nanosheets were successfully synthesized from layer compound of Tb₂(OH)₅NO₃·1.5H₂O doped by Eu³⁺. Firstly layer compound of Tb₂(OH)₅NO₃·1.5H₂O doped by Eu³⁺ was obtained by hydrothermal reaction at 120⁰ . After ion exchange reaction with SDS under the microwave condition, the layer space of the compound increases from 0.907 nm to 2.34 nm. Furthermore stable nanosheet sol was obtained after exfoliation under ultrasonic condition. At the mean time we discovered that microwave and ultrasonic method can greatly shorten the preparation time. The structure of layer compound and the morphology of nanosheets were determined by XRD and TEM. The luminescence properties of terbium hydroxide nanosheets doped with Eu³⁺ were examined; the relationship between structure and spectra was discussed
