研究目的
Comparison of vanadium oxide thin films deposited from commercial and solution combustion synthesised powders, focusing on their structural, morphological, optical, and electrochemical properties.
研究成果
The research demonstrated that solution combustion synthesised V2O5 powder produces thin films with superior optical transmittance, electrochemical properties, and coloration efficiency compared to those made from commercial powder. These findings suggest potential applications in electrochromic devices and other nanoscale optoelectronic devices due to the films' reproducibility, cost-effectiveness, and rapid fabrication process.
研究不足
The study acknowledges the non-uniformity in film thickness due to centrifugal force during spin coating, which could affect the optical and electrochemical measurements. Additionally, the intercalation of Na+ from the glass substrate into the film was noted as a factor influencing the film's properties.
1：Experimental Design and Method Selection:
The study utilized the sol–gel spin coating method for thin film deposition, chosen for its cost-effectiveness and simplicity.
2：Sample Selection and Data Sources:
Both commercial and solution combustion synthesised V2O5 powders were used as precursors.
3：List of Experimental Equipment and Materials:
Instruments included a PANalytical X’pert PRO X-ray diffractometer, Quanta 250 FEGSEM Scanning Electron Microscope, Dektak 150 Profilometry, Philips X-ray diffractometer, JEOL JSM-5410, NKD 7000 model spectrophotometer, and Parstat 2263 cyclic voltammetry. Materials included ammonium metavanadate, citric acid, hydrogen peroxide, and substrates like Corning glass and ITO-coated glass.
4：Experimental Procedures and Operational Workflow:
The process involved powder synthesis via SCS, sol–gel preparation, spin coating on substrates, and annealing.
5：Data Analysis Methods:
Structural analysis was performed using XRD, morphological properties via SEM, optical properties through spectrophotometry, and electrochemical properties via cyclic voltammetry.
