Zusammenfassung:In response to ever‐increasing application requirements in lighting and displays, a tremendous emphasis is being placed on single‐component white‐light emission. Single‐component inorganic borates doped with rare earth metal ions have shown prominent achievements in white‐light emission. The first environmentally friendly defect‐induced white‐light emitting crystalline inorganic borate, Ba2[Sn(OH)6][B(OH)4]2, has been prepared. Additionally, it is the first borate‐stannate without a Sn−O−B linkage. Notably, Ba2[Sn(OH)6][B(OH)4]2 shows Commission Internationale de l'Eclairage (CIE) chromaticity coordinates of (0.42, 0.38), an ultrahigh color rendering index (CRI) of 94.1, and an appropriate correlated color temperature (CCT) of 3083 K. Such a promising material will provide a new approach in the development of white‐light emitting applications. The first borate‐stannate, which is also the first environmentally friendly defect‐induced white‐light emitting crystalline inorganic borate, Ba2[Sn(OH)6][B(OH)4]2, has been prepared. It shows CIE chromaticity coordinates of (0.42, 0.38), an ultrahigh CRI of 94.1, and an appropriate CCT of 3083 K.
