RE-doped ferrite/carbon hybrids for synergistic enhancement of broadband microwave absorption and dual-band laser suppressionOA
The rapid evolution of multispectral detection systems requests stealth materials capable of simultaneously delivering strong microwave absorption and suppressed nearinfrared laser reflection.This study proposes a novel rare earth(RE)doping strategy to construct a heterostructures ternary Fe_(3)O_(4)@C/REOCl(RE=Sm,Er,Dy,and Ho)through in-situ assembly-thermal reduction process.The optimized Fe_(3)O_(4)@C/REOCl demonstrates exceptional multi-spectral modulation capabilities due to the synergistic effects of multicomponent dielectric loss,magnetic loss,and RE spectral modulation.The Sm^(3+)-modified system(FCS)achieved effective absorption bandwidth of 5.41 GHz at 1.5 mm,and the Ho^(3+)-modified system(FCH)exhibited ultralow laser reflectivity of 1.86%and 1.98%at the wavelength of 1.06 and 1.55μm.This study introduces a unified framework that facilitates broadband microwave absorption(>5 GHz)and dual-band laser suppression(<2%).It establishes a universal model that can be adapted to various RE components and scalable fabrication pathways for multi-spectral stealth materials.
