Crystalline bismuth oxide nanorods fabricated on Pt‐coated substrates using a trimethylbismuth and oxygen mixture

Abstract

The current work reports the fabrication of crystalline Bi 2 O 3 nanorods on Pt-coated Si substrates using trimethylbismuth and O 2 as the bismuth and the oxygen sources, respectively, in the metalorganic chemical vapor deposition process. Their microstructures were characterized by scanning electron microscopy, X-ray diffraction, and transmission electron microscopy. The obtained nanorods were crystalline, with their diameters in the range of 20-200 nm. The absence of tip-nanoparticle and the presence of predeposited Bi 2 O 3 layer indicated that the growth was dominated by a vapor-solid process. The photoluminescence measurements of the Bi 2 O 3 nanorods at room temperature exhibited an emission band peaked at around 422 nm.

Magnetic and FTIR studies of BixY3−xFe5O12 (x=0, 1, 2) powders prepared by the metal organic decomposition method

“…In our experiment, the existence of the maghemite phase up to 700 • C may be explained by the same reason: Y 2 O 3 would stabilize the maghemite phase by interaction with iron ions. [18], and a minor phase, ␥-Fe 2 O 3 . In the case of x = 2, there are three phases: [19] and ␥-Fe 2 O 3 , and the t-YBFO phase was stronger than the ␥-Fe 2 O 3 phase.…”

“…Further characterization of the bismuth oxide powder used in preparing the modified electrode with XRD confirmed it as having a crystalline phase with the XRD pattern revealing similar intense peaks comparable to those reported by other researchers. [21,22].…”

“…So at 500 1C, the b-Bi 2 O 3 phase disappeared and the g-Fe 2 O 3 remained up to 700 1C. Sintered powder at 500-600 1C shows several diffraction peaks, and this pattern can be thought as a superposition of g-Fe 2 O 3 , YFeO 3 [20], and BiFeO 3 [13], being a major attribution, while a weak presence of some kind of oxides; a-Fe 2 O 3 , a-Bi 2 O 3 [21], Y 2 O 3 [22], etc. are seen.…”
