Broadband and Enhanced Second‐Harmonic Generation in Metallic 3R‐TaS2

open access: yesSmall, Volume 22, Issue 53, 21 September 2026.
A pronounced and robust SHG response has been observed in metallic 3R‐TaS2. It shows broadband SH conversion from 1020 nm to 1410 nm. Moreover, compared to the sapphire substrate, 3R‐TaS2 flakes with various thicknesses on the gold substrate showed different SHG enhancement; the enhancement factors range from 2.7 to 45.5.

Self‐Assembly Enabled Mie‐Scattering in Hematite Nanoplatelet Stacks

open access: yesNanophotonics, Volume 15, Issue 16, 26 August 2026.
The spectral evolution during the electrolyte‐induced self‐assembly of 120 × 20 nm hematite nanoplatelets into vertical stacks in aqueous solutions is investigated. Optical simulations and correlative electron microscopy/single particle spectroscopy confirm that a collective magnetic dipole mode develops in the assembling stacks.
