1：Experimental Design and Method Selection:
The spray pyrolysis technique (SPT) was used to grow graphene oxide (GO) thin films on glass substrates. The method is simple, low cost, and effective.
2：Sample Selection and Data Sources:
GO was synthesized using the modified Hummers method. Glass substrates were cleaned using methanol and ultrasonication.
3：List of Experimental Equipment and Materials:
Airbrush nozzle, timer, beaker solution, thermocouple probe, hot plate heater, air pump compressor, Philips X-ray diffractometer, SEM Model Quanta 250 FEG, Nicolet 6700 Spectrophotometer, JASCO model V-670 UV-Vis-NIR.
4：Experimental Procedures and Operational Workflow:
GO dispersion in deionized water was spray-coated onto glass substrates at 170°C. The distance between the nozzle and substrate was 40 cm.
5：Data Analysis Methods:
Raman spectroscopy, XRD, FESEM, and UV–visible spectroscopy were used to analyze the structural and optical properties of the GO thin films.
