Sb‐Doped Cs3TbCl6 Nanocrystals for Highly Efficient Narrow‐Band Green Emission and X‐Ray Imaging (Adv. Mater. 2/2024)

Lanthanide Halide Nanocrystals Novel luminescent 0D lanthanide halide nanocrystals with bright narrow-band green emission are reported by Peigeng Han, Kun Zhao, Ruifeng Lu, and co-workers in article number 2302140. The introduction of an ns2-cation dopant not only optimizes the crystallinity, but also greatly boosts the photoluminescence efficiency up to 48.1%. Furthermore, Cs3TbCl6:2.5%Sb nanocrystals are proved to serve as a promising nanoscintillator, which has versatile application prospects for lighting and X-ray imaging.
