Stutural, dielectric and optical properties of BBLT. (a) Reitveld refined XRD pattern recorded at 300 K and (b) temperature-dependent ε′ plotted at different frequencies for the BBLT sample. The inset shows the dielectric loss factor at 10 kHz. (c) The reflectance spectrum of the BBLT sample. The inset shows the corresponding Kubelka–Munk plot.
