Application of Laser Raman Spectroscopy of Ferroelectric Nanomaterial BaTiO3 in the Design of Color Spotlight Products on Stage

Abstract

With the improvement of people’s material requirements, the demand for lighting materials is higher and higher. This study mainly discusses the application of the laser Raman spectroscopy of ferroelectric nanomaterial BaTiO3 in the design of color spotlight products on the stage. Firstly, the effects of different electrospinning parameters on BaTiO3 nanofibers were studied. Then, the samples were spun under the best spinning parameters and annealed at 600°C, 650°C, 700°C, and 750°C, and then the phase structure, morphology, and piezoelectric properties of the samples at four different annealing temperatures were characterized. In this study, the laser Raman signal converges to the incident slit of the monochromator through the lens. After grating splitting, the signal is obtained through CCD. Finally, the spectral curve is recorded by the computer-controlled data acquisition software winspec/32 and saved as an .spe file. The spectral data to be processed need to be smoothed. The luminescence intensity of BaTiO3 with flower structure is weak, which is mainly caused by the different crystal forms of the matrix. By analyzing the content of each element, it is found that BA/Ti = 1/2, and it can be inferred that the proportion of BaTiO3 and TiO2 is about 6%. The XRD spectra of the samples obtained at different temperatures (−25, 0, 30, 50, and 70°C) corresponded to the standard card BaTiO3 one-to-one, and no impurity peaks were found, indicating that the obtained samples are pure phases. This research will promote the application of nanomaterials in color spotlight products.
