Abstract

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.
