Abstract
Abstract Group 14 nanocrystals (NCs) have gained significant attention in the last decade largely owing to their unique and tunable optoelectronic properties, allowing for diverse applications across a range of fields. Herein we report a gram‐scale method to prepare Si and Ge NCs from mesoporous metal oxides using a solid‐state metallothermic reduction method. Mesoporous SiO 2 and GeO 2 were prepared using a templated sol‐gel method. The influence of pore size of the metal oxide precursor and the nature of reducing metal on the formation of Si and Ge was investigated. The NCs were functionalized with dodecyl groups via microwave‐assisted hydrosilylation and hydrogermylation reactions, respectively. Si and Ge NCs were found to have tunable visible or near‐IR luminescence with high emission quantum yields.

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
