Multichannel detection x-ray absorption near edge structures study on the structural characteristics of dendrimer-stabilized CdS quantum dots
Bibliographic record
Abstract
Starburst poly-(amidoamine) dendrimers were used to obtain dendrimer stabilized CdS nanoparticles, or quantum dots (QDs). The average particle size of the QDs was examined by UV-vis absorption spectra and powder x-ray diffraction measurements. The technique of x-ray absorption near edge structure (XANES) near the S K-edge was employed to study the structural characteristics of a series of QDs. The use of a multichannel detection scheme in XANES, monitoring total electron yield, x-ray fluorescence yield, and photoluminescence yield simultaneously, was demonstrated to be a powerful tool to evaluate the structure of the QDs from a sulfur perspective. The relationship between the luminescence property and the local structure of sulfur in the QDs was also discussed on the basis of the results of x-ray excited optical luminescence and XANES studies.

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.
