Bimetallic Bismuth-Based Nanoparticles From Pseudo-Tetrahedral Zintl Anions. [PDF]

open access: yesSmall
Bismuth‐based Zintl anions are explored as precursors for synthesizing bimetallic nanoparticles with tunable compositions and morphologies, including alloyed, core–shell, and Janus types. The resulting nanoparticles display composition‐dependent UV absorption.
