Abstract
High-quality platelet α-MoO3 single crystals with dimensions of ∼1000×200×0.4μm3 have been grown on Si(100) substrates in quartz tube reactor in air atmosphere by sublimation of molybdenum oxide at T=660°C. Phase composition of grown crystals has been identified by X-ray single crystal structure analysis in space group Pnma, a=13.8674(7) Å, b=3.6976(2) Å, c=3.9644(2) Å, Z=4 (R=0.0154). Polarized Raman microspectrometry has been used to describe the symmetry of vibration modes of α-MoO3 Raman spectrum. Several Raman lines as narrow as ∼2cm−1 have been measured for α-MoO3 crystal.
