Abstract

Crystalline terbium-doped indium hydroxide structures were prepared by a rapid and efficient Microwave-Assisted Hydrothermal (MAH) method. Nanostructures were obtained at a low temperature. FE-SEM images confirm that these samples are composed of 3D nanostructures. XRD, optical diffuse reflectance and photoluminescence (PL) measurements were used to characterize the products. Emission spectra of terbium-doped indium hydroxide (In(OH)₃:xTb³⁺) samples under excitation (350.7 nm) presented broad band emission referent to the indium hydroxide matrix and ⁵D₄ → ⁷F₆, ⁵D₄ → ⁷F₅, ⁵D₄→ ⁷F₄, and ⁵D₄→ ⁷F₃ terbium transitions at 495, 550, 590 and 627 nm, respectively. Relative intensities of the Tb³⁺ emissions increased as the concentration of this ion increased from 0, 1, 2, 4 and 8 mol%, of Tb³⁺, but the luminescence is drastically quenched for the In(OH)₃ matrix.
