Structural and physical properties of NbO2 and Nb2O5 thin films ...
2019年4月29日 · X-ray diffraction (XRD) and Raman spectroscopy confirmed the tetragonal phase of NbO2 and orthorhombic phase of Nb2O5 for similar deposition temperatures. Scanning electron microscopy (SEM) observations indicate that NbO2 has a unique nanoslice structure while Nb2O5 has a flake-like structure.
Preparation and spectroscopic properties of Nb2O5 nanorods
2008年8月1日 · Nb 2 O 5 nanorods have been prepared using water/ethanol media. The samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV–visible absorption and photoluminescence spectroscopy. The as-prepared Nb 2 O 5 nanorods appeared to be single pseudohexagonal (TT-Nb 2 O 5) phase.
