XRD and Raman study of vanadium oxide thin films deposited on fused silica substrates by RF magnetron sputtering

Low temperature fabrication of vanadium oxide films for uncooled bolometric detectors

“…VO 2 (B) is a metastable compound of VO 2 and has no phase transition properties near room temperature. The dominant of VO 2 (B) in the as-deposited film may be caused by the low deposition temperature and ours results are in substantial agreement with that of Wang [12]. Comparison of XRD patterns of annealed and unannealed films indicate clearly that a transformation of VO 2 (B) to VO 2 takes place during annealing process, and such VO 2 (B) to VO 2 phase transformation has also been observed and reported by Takahashi [13].…”

Structural, optical and ferroelectric properties of V doped ZnO

“…Some Raman peaks are also observed towards lower frequencies at 136 and 190 cm -1 especially for higher concentration, appear due to the stretching mode of (V 2 O 2 ) n which correspond to the chain translation (Juloen et al 1997). The peak at 255 cm -1 is broad in nature and may be due to V-O-V bending mode (Wang et al 2001). Actually this peak consists of more than one peak.…”

Mesoporous vanadium oxide nanostructures: Hydrothermal synthesis, optical and electrochemical properties

“…According to the literature, these bands can be assigned to the fundamental modes of crystalline VO 2 (B) monoclinic. The band at 148 cm À 1 is attributed to the stretching mode of (V 2 O 2 ) n which correspond to the chain translation [38][39][40]. The bands located at 408 and 287 cm À 1 are assigned to the bending vibration of the VQO bonds [41].…”
