Optical Limiting in Cu/CuO Nanostructures Formed by Magnetic Field-Assisted Anodization
Bibliographic record
Abstract
The recently developed magnetic field-assisted electroless anodization technique enables more morphological tunability by expanding the parameter space available during nanostructure synthesis and limiting the effects of copper electromigration. We synthesized CuO nanodendrites, nanowalls and nanospheres on both transparent and non-transparent substrates using the magnetic field-assisted anodization of copper foils and vacuum deposited Cu thin films on glass substrates respectively. Non-linear optical characterization of the resulting partially transparent Cu/CuO nanostructures on glass substrates revealed clear optical limiting behavior. When the fluence of the incident 800 nm radiation from a Ti:sapphire laser was increased from 20 mJ cm −2 to 2 J cm −2 , the optical transmittance of the Cu/CuO nanostructures decreased by nearly an order of magnitude.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
