Abstract
Abstract The control of the shapes and assembling structures of plasmonic nanoparticles is vital for the optical properties and photothermal conversion performance. Here, gold nanospheres and nanostars are assembled into ridges/disordered nanohole arrays architecture in nanoparticle colloids using light‐trapping Papilio Paris forewings (OPPs) as templates. In solar steam generation, water evaporation efficiency reaches 83.3% for nanostar assemblies (NSAs) and 68.6% for nanosphere assemblies (NSPAs) under 1‐sun (1 kW m −2 ) irradiation. Both the biomimetic superstructures exhibit significant enhancement of near‐infrared light absorption compared to OPPs, and NSAs show higher absorption than NSPAs in the range of 200–2500 nm. Finite element method simulations reveal such broadband absorption is ascribed to the hybridization of localized surface plasmon modes of continuous‐assembled Au nanoparticles in the biomimetic structures as well as the wing photonic structures with light‐transferring ridges with an inverted V shape and light‐trapping disordered nanohole arrays. It is revealed that optical properties of superstructures can be tuned not only by controlling their 3D structures but also by changing the shape of nanosized building blocks. It is hoped that this work will provide inspirations for the design and assembly of nanophotonic structures and devices for solar energy conversion.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
