The rods, of rectangular cross section, are composed of weakly bonded stacks of tiny plates of few hundreds of nanometres, which self-assembled during the growth process parallel to the growth axis. Photoluminescence (PL) spectra show resonance peaks in the ultraviolet-blue region related to optical cavity modes across the cross sections of the rods. Local phase transformation from the orthorhombic to the cubic Sb_2O_3 phase has been induced by long irradiation with the 325 nm laser light, as confirmed by Raman spectroscopy and PL.engjournal articlehttp://dx.doi.org/10.1007/s11051-013-1667-5http://link.springer.comopen access538.9Antimony TrioxideCrystal-StructureNanorodsNanowiresGrowthFilmsOxideFísica de materiales
