Abstract
Silica-coated and uncoated, Tb-doped (1-5 at % Tb) Y(2)O(3) green nanophosphors were made, for the first time, in a single step by flame aerosol technology with controlled crystal phase (cubic and monoclinic) and morphology. The nanophosphors were characterized by X-ray diffraction, N(2) adsorption, high resolution electron microscopy, and photoluminescence spectroscopy. The monoclinic crystal structure of Y(2)O(3):Tb(3+) nanophosphors favors the electric dipole (5)D(4) → (7)F(5) transition driving their green phosphorescence. The phosphorescence of the SiO(2)-coated monoclinic Y(2)O(3):Tb(3+) nanophosphors is lower than the uncoated ones. Upon annealing these nanophosphors, they were transformed from monoclinic to cubic and their phosphorescence was reduced. This further indicates the superior performance of the monoclinic crystal phase for the electric dipole transitions of Tb(3+) ions.

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
