Abstract
- Abstract: Highly crystalline orthorhombic Sb2O3 nano-rods were prepared at room temperature by hydrolysis of SbCl3 in iso-propanol. Morphology induced changes in the photoluminescence properties of both the, as prepared as well as the annealed ones (at different temperatures) are presented. A distinct photoluminescence-band observed over the region of 500–600nm is arising due to the morphology of Sb2O3 nano-rods. Changes in the Raman spectrum at ∼260 and 445cm−1, corresponding to the Sb3+–O–Sb3+ stretching and bending modes, further confirm their shape selective nature. This study reveals significant effect of morphology on the structural and luminescent properties of Sb2O3. [Copyright &y& Elsevier]
