Abstract

Abstract : Bundle-shaped TbPO4 ·H2 O nanorods have been prepared by a facile hydrothermal technique and characterized by XRD, SEM, TEM, UV-Vis diffuse reflectance spectrum (DRS), photoluminescence (PL) spectrum, and lifetime. The results indicate that the obtained sample has hexagonal structure of TbPO4 ·H2 O and is composed of nanorods bundles which is assembled from many single crystalline nanorods with the diameter of around 45 nm and the length of 2.3 μ m. The growth of the single crystalline nanorod is along the (001) plane direction. Under the UV light irradiation, TbPO4 ·H2 O nanorods bundles exhibit bright green emission corresponding to the D 5 4 → F 7 J (J = 6, 5, 4, 3 ) transitions of the Tb 3+ ions, and the lifetime is determined to be about 0.24 ms.
