研究目的
Investigating the production of three-dimensional ZnO multilayered structures from self-assembled ZnO microdiscs using the spray pyrolysis method for applications in gas sensors, electronic devices, and solar cells.
研究成果
ZnO three-dimensional multilayered microstructures were successfully produced using the spray pyrolysis technique. These structures offer a large surface area, which is beneficial for applications in solar cells, gas sensors, and optoelectronic devices. The presence of chlorine in the films was noted, which could influence their properties.
研究不足
The EDS quantification of rough materials can have large errors, and the assumptions for quantitative analysis may not hold for rough samples like the films under study.
1：Experimental Design and Method Selection:
The spray pyrolysis method was used to deposit ZnO thin films on glass substrates at a substrate temperature of 350 ± 5°C.
2：Sample Selection and Data Sources:
Glass substrates of 60 × 26 × 1 mm3 dimensions were used.
3：List of Experimental Equipment and Materials:
A Shimadzu XRD-7000 diffractometer, FEI scanning electron microscope (SEM) (Inspect F 50), and x-ray energy dispersion spectroscopy (EDS) were used.
4：Experimental Procedures and Operational Workflow:
The films were characterized using XRD, SEM, and EDS to determine their structure, morphology, and composition.
5：Data Analysis Methods:
ImageJ software was used to estimate the edge of the hexagons and the distribution of measurements.
