Hydrothermal synthesis, characterization, and optical properties of Ce doped Bi<inf>2</inf>MoO<inf>6</inf>nanoplates

Abstract

Undoped and Ce doped Bi2MoO6samples were synthesized by hydrothermal reaction at 180°C for 20 h. Phase, morphology, atomic vibration, and optical properties were characterized by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectrophotometry, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), selected area electron diffraction (SAED), and UV-visible spectroscopy. In this research, the products were orthorhombic Bi2MoO6nanoplates with the growth direction along the [0b0], including the asymmetric and symmetric stretching and bending modes of Bi-O and Mo-O. Undoped and Ce doped Bi2MoO6samples show a strong absorption in the UV region. © 2014 Anukorn Phuruangrat et al.
