Shell Engineering of ITO Nanocrystals via Seed-Mediated Growth and Precursor Crowding for Broadband Visible- to-Infrared Absorption.

ABSTRACT: Seed-mediated growth strategies provide a powerful platform for constructing complex nanocrystal architectures by enabling controlled shell deposition on preformed cores. Here, we report a modular synthesis of multicomponent metal oxide nanocrystals featuring compositionally modulated core-shell architectures. Specifically, indium tin oxide (ITO) nanocrystals are engineered through sequential shelling combined with tunable precursor crowdinga strategy analogous to molecular crowdingthat reinforces the local precursor concentration near the nanocrystal surface. This environment promotes diffusion-limited growth and enables anisotropic shell formation along with controlled incorporation of otherwise inaccessible transition metal dopants. Undoped shells transform from quasi-spherical to fac
