Abstract
Abstract Direct synthesis of luminescent SiC quantum dots in pure deionized water by laser ablation is reported. A zeta‐potential of –49 mV, higher than for nanoparticles produced by electrochemical etching, suggests a higher colloidal stability of the laser‐produced nanoparticles. IR spectroscopy shows that surface charges related to carboxylate anions ensure long‐term stability of the colloidal solutions based on the as‐prepared SiC quantum dots. Main radiative channel at room temperature corresponds to the recombination of quantumly confined photogenerated charge carriers. Emission from the nanoparticles is mainly centred at 2.75 eV regardless of laser power used for ablation. According to photoluminescence spectra, a partial transformation of the SiC quantum dots from cubic to hexagonal crystalline arrangement is supposed. (© 2011 WILEY‐VCH Verlag GmbH & Co.

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
