The data of the article "Preparation of Wrinkled Hexagonal Boron Nitride Films by Bubbling Chemical Vapor Deposition"

Raman spectroscopy (Raman, Renishaw inVia) was employed to measure the characteristic peak of the E2g vibration mode of h-BN. The raw data were processed using the Lorentzian fitting method to analyze the peak shift and full width at half maximum (FWHM), thereby evaluating the thickness and crystalline quality of the product.

An X-ray diffractometer (XRD, Shimadzu XRD-6100) was used to characterize the crystal structure of the h-BN powder. A Fourier transform infrared spectrometer (FTIR, Thermo Scientific Nicolet iS50) was utilized to characterize the typical characteristic absorption peaks of h-BN and detect surface-adsorbed functional groups. The ultraviolet-visible absorption spectrum of h-BN was characterized using an ultraviolet-visible absorption spectrometer (UV-Vis, HORIBA NanoLog) to determine its optical bandgap.
