Synthesis & material properties of α-MoO3 nanoparticles

Abstract In the interesting class of transition metal oxides, molybdenum oxides and its derivatives are exceptionally anticipated because of their particular optical and structural properties. At room temperature, molybdenum trioxide is a wide band gap semiconductor with enhanced exciton binding energy. In nature, MoO3 in three forms which are α, β and h-forms (α-orthorhombic, β-monoclinic, h- hexagonal phase). The synthesis and material properties of α-MoO3 nano crystals are reported under this study. Localized surface Plasmon resonance is a resonance with incident light of co-operative oscillations of free charge carriers in nano range material (LSPR). Such kind of plasmonic interactions exhibit by MoO3 nanoparticles due to movement of electron at different defect states. This concept has been used in to several functional materials and devices. We efficaciously synthesised α-MoO3 by one-pot hydrothermal route. Arranged nano sheet like structure was found as assured by FESEM. The synthesised nanostructure revealed noble optical and structural properties which was confirmed by X-ray diffraction (XRD), Field emission Scanning electron microscopy (FESEM), Ultra violet-Visible technique (UV–VIS), Fourier transform Infra-red (FT-IR) data. Energy dispersive X-ray spectrum (EDS) showed elemental composition present in synthesized material with no contaminants.
