Abstract
Nano-sized Sr2MgSi2O7: Eu2+,Dy3+ phosphor with long lasting behavior was synthesized by a sol-gel method. The chemical reaction process during calcination, and the luminescent property of the obtained phosphor, were investigated in detail. The result indicated that the phosphor obtained by the sol-gel method, which showed photoluminescence and long lasting behavior, was consisted of nano-sized grains about 50nm. The sol-gel-derived phosphor gave out a visible light upon UV illumination peaking at 465nm, while the phosphor obtained by solid reaction showed two emission peaks upon UV irradiation at 404nm and 459nm respectively. The difference in emission spectra can be ascribed to the different coordinators formed within the silicate matrix. The phosphor synthesized by solid reaction exhibited a better afterglow character than the phosphor obtained by the sol-gel method, due to a higher trap concentration which was formed by a higher reaction temperature.

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; both teacher heads agree on what is shown here.
