Abstract

Vanadium dioxide (VO2) shows excellent thermochromic properties suitable for potential application in optical devices and smart windows coating. VO2 is interesting since actual coating on glass materials is possible along with large-scale production. This paper, VO2 nanoparticles were synthesized successfully using the sol-gel-assisted hydrothermal method. The as-prepared VO2 nanoparticles were annealed under vacuum, and the crystal phase formation, composition, morphology, and metal-insulator phase transition properties of the nanoparticles were studied. X-ray Diffraction (XRD) spectra revealed that a purely monoclinic phase of VO2 nanoparticles with an average crystallite size of 33.27 nm was synthesized. Scanning Electron Microscopy (SEM) micrographs also confirmed the formation of crystalline VO2 nanoparticles. Differential Scanning Calorimetry (DSC) curve shows that the change in temperature (∆T_c) between the exothermic and endothermic peaks is 13ºC. Moreover, Fourier Transform Infrared (FTIR) spectroscopy peaks ascertain the presence of VO2 functional groups in the synthesized nanoparticles.

二氧化钒纳米粒子的一锅水热合成

二氧化钒（VO2）表现出优异的热致变色性能，适用于光学器件和智能窗户涂层的潜在应用。VO2是令人感兴趣的，因为随着大规模生产，在玻璃材料上的实际涂层是可能的。本文采用溶胶-凝胶辅助水热法成功合成了VO2纳米粒子。将制备的VO2纳米颗粒在真空下退火，研究了纳米颗粒的晶相形成、组成、形貌和金属-绝缘体相变性能。X射线衍射（XRD）光谱显示，合成了平均晶粒尺寸为33.27nm的纯单斜相VO2纳米颗粒。扫描电子显微镜（SEM）显微照片也证实了结晶VO2纳米颗粒的形成。差示扫描量热法（DSC）曲线显示，放热峰和吸热峰之间的温度变化（∆T_c）为13ºc。此外，傅立叶变换红外（FTIR）光谱峰确定了合成的纳米颗粒中VO2官能团的存在。
