Fig. 1: Design and morphological characterization of nanorods: directionally coating of active shell and inert shell with the same scale.

From: Understanding shell coating effects to overcome quenching in single anisotropic upconversion nanoparticles

Fig. 1

a Schematic diagram illustrating the routes of directional growth of active shell or inert shell onto CR (Core Rod) sample. b−e TEM images and size distributions displaying the morphology after directional coating of active and inert shell. D refers to diameter, and L refers to length. Scalebar: 100 nm. For (c) and (e) the indicated error represents the standard deviation (SD) from 100 independent nanoparticle measurements. Colors in the Figure differentiate sample groups according to their surface coatings: yellow tones correspond to nanoparticles coated with active shells, and gray tones correspond to nanoparticles coated with inert shells. Different shades within each group reflect individual sample batches. Source data are provided as a Source data file.
