Boron Doping of Silicon Quantum Dots via Hydrogen Silsesquioxane-Capped Diffusion for Photovoltaics and Medical Imaging
Bibliographic record
Abstract
Doped silicon quantum dots (SiQDs) with defined size, dopant distribution, and surface chemistry are highly sought after as a scientific curiosity because their unique properties offer a wide array of potential applications including multimodal medical imaging and photovoltaic devices. This report describes a diffusion-based postsynthesis doping method for incorporating high concentrations of B (2.5–5.0 at. %) into preformed SiQDs of predefined sizes while simultaneously maintaining their structure and morphology. The processing temperature, atmosphere, and QD size all strongly influence the resulting B-doped SiQDs. The as-synthesized doped SiQDs exhibit size-dependent photoluminescence spanning the visible to near-infrared spectral regions, are compatible with aqueous environments, and are readily rendered compatible with organic solvents upon functionalization with appropriate alkoxide surface groups. Being able to effectively tune the size and surface chemistry of the present B-doped SiQDs make them excellent candidates for use in targeted applications such as multimodal imaging and photovoltaic devices.

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.
