Orthorhombic Molybdenum Trioxide Whiskers by Vapor Transport Method

Orthorhombic MoO3 whiskers have been grown by using vapor transport method. High-quality, transparent and colorless MoO3 plate-like whiskers are obtained inside alumina furnace tube with high aspect ratio of 20-30 for the growth time of 1 h. The length and the width of whiskers are directly proporti...

Description
Summary:Orthorhombic MoO3 whiskers have been grown by using vapor transport method. High-quality, transparent and colorless MoO3 plate-like whiskers are obtained inside alumina furnace tube with high aspect ratio of 20-30 for the growth time of 1 h. The length and the width of whiskers are directly proportional to growth time. The location that whiskers occurred is an evidence of vapor-solid growth mechanism by sublimation. From characterization, MoO3 whiskers exhibit a near-perfect single crystal with high purity of orthorhombic phase, smooth morphology, and indirect band gap of 2.98 eV. MoO3 whisker has also been demonstrated as a gas sensor toward ethanol vapor.
