Figure Lengend Snippet: a Scanning electron microscopy (SEM) image of synthesized BSTON(TN0.2) solid-solution particles. b X-ray diffraction (XRD) pattern for the same sample. c Enlarged view of (110) diffraction peak region. The blue and green bars indicate the (110) peak positions for BaTaO 2 N (JCPDS card No. 40-0566) and SrTaO 2 N (JCPDS card No. 40-0662), respectively. d Ultraviolet-visible (UV–Vis) diffuse-reflectance spectrum of BSTON(TN0.2). e Annular dark-field scanning transmission electron microscopy (ADF-STEM) image and the corresponding energy-dispersive X-ray spectroscopy (EDS) elemental maps for synthesized BSTON(TN0.2) solid-solution particles. Source data for Fig. 1b, d are provided as a file.
