We summarize the current knowledge on crystal structures, synthesis, applications, and Raman spectroscopy of Wadsley phases of vanadium oxide, including VO₂ (B), V₆O₁₃, V₄O₉, V₃O₇, and V₂O₅. While these oxides have garnered significant attention for potential energy storage applications and have been studied for decades, there remains inconsistency in data regarding their characteristic Raman spectra. To address this, we synthesized a series of Wadsley phases by physical vapor deposition of amorphous vanadium oxide films and subsequent annealing in a controlled environment. X-ray diffraction studies confirmed the formation of VO₂ (B), V₆O₁₃, V₄O₉, and V₃O₇. We meticulously measured the room-temperature Raman spectra of these phases, offering robust reference data for the easy identification of vanadium oxides in unknown samples. Finally, we studied low-temperature phase transitions in VO₂ (B) and V₆O₁₃.

氧化钒沃兹利相的拉曼光谱

_{我们总结了目前关于氧化钒沃兹利相（包括 VO 2} (B)、V ₆ O ₁₃、V ₄ O ₉、V ₃ O ₇和 V ₂ O _{5 ）}的晶体结构、合成、应用和拉曼光谱的知识。。虽然这些氧化物在潜在的能量存储应用方面引起了极大的关注，并且已经研究了数十年，但有关其特征拉曼光谱的数据仍然不一致。为了解决这个问题，我们通过物理气相沉积非晶氧化钒薄膜并随后在受控环境中退火合成了一系列沃兹利相。 X射线衍射研究证实了VO ₂ (B)、V ₆ O ₁₃、V ₄ O ₉和V ₃ O ₇的形成。我们仔细测量了这些相的室温拉曼光谱，为轻松识别未知样品中的钒氧化物提供了可靠的参考数据。最后，我们研究了VO ₂ (B)和V ₆ O ₁₃的低温相变。
