Abstract
Sm 3+ doped Sb 2Se 3 nanorods were synthesized by the co-reduction method at 180 °C and pH=12 for 48 h. Powder XRD patterns indicate that the Sm x Sb 2− x Se 3 crystals ( x=0.00–0.05) are isostructural with Sb 2Se 3. The cell parameters increase for Sm 3+ upon increasing the dopant content ( x). SEM images show that doping of Sm 3+ ions in the lattice of Sb 2Se 3 results in nanorods. High-resolution transmission electron microscopic (HRTEM) studies reveal that the Sm 0.05Sb 1.95Se 3 is oriented in the [1 0 −1] growth direction. UV–vis absorption reveals mainly electronic transitions of the Sm 3+ ions in doped nanomaterials. Emission spectra of doped materials, in addition to the characteristic red emission peaks of Sb 2Se 3, show other emission bands originating from f–f transitions of the Sm 3+ ions. The electrical conductance of Sm-doped Sb 2Se 3 is higher than undoped Sb 2Se 3 and increase with temperature.
