Abstract
Exploiting the chemical compatibility of transparent high surface area silica aerogels and environmentally benign luminescent silicon nanocrystals (SiNCs) opens the door to a new class of silicon-based hybrid materials. Hydrophilic SiNCs of various sizes and surface groups that photoluminesce throughout the visible and NIR spectral regions were synthesized and incorporated into a tetramethyl orthosilicate containing solution to produce luminescent aerogels of varied transparency. Photoluminescence (PL) spectroscopy performed on solutions and aerogel monoliths containing SiNCs reveal that the optical properties of SiNCs are dependent on their size and surface chemistry. Furthermore, the incorporation of SiNCs into aerogels does not influence their PL response. The nitrogen adsorption–desorption measurements indicate that the physical properties of aerogels may be tailored by changing the SiNC size and surface chemistry. Adding to the appeal of the present work, PL quenching of SiNC-loaded aerogel upon exposure to nitrobenzene confirms that SiNCs remain chemically accessible.

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
