dc.description.abstractRare earth ion (Lu3+, Ho3+, Nd3+)-doped Sb2Se3 nanomaterials are synthesized by a co-reduction method in hydrothermal condition. Powder XRD patterns indicate that the Ln(x)Sb(2-x)Se(3) crystals (Ln = Lu3+, x = 0.00-0.12; Ho3+, x = 0.00-0.1 and Nd3+, x = 0.00-0.09) are isostructural with Sb2Se3. SEM images show that doping of Ho3+ ions in the lattice of Sb2Se3 results in nanorods while that in Nd3+ and Lu3+ leads to nanoflowers and nanoparticles, respectively. High-resolution transmission electron microscopic (HRTEM) studies reveal that the Sb2Se3 and SB1.90 Ho0.1Se3 are oriented in the [10-1] growth direction. UV-vis spectra show that an increasing concentration of Ln(3+) ions increases the intensity of some peaks in the absorption spectrum of Sb2Se3 related to electronic transitions of the Ln(3+) ions in case of Ho3+ and Nd3+ doped nanomaterials. Emission spectra of doped materials, in addition to the characteristic red emission peaks of Sb2Se3, show other emission bands originating from f-f transitions of the Ho3+ ions. The electrical conductance of Ln-doped Sb2Se3 is higher than the undoped Sb2Se3, and increases with temperature. (C) 2011 Elsevier B.V. All rights reserved.-
