Abstract

fetched live from OpenAlex

The effect of silica-capping on the afterglow property of Sr 2 MgSi 2 O 7 :Eu,Dy nanoparticles was investigated. Sr 2 MgSi 2 O 7 :Eu,Dy nanoparticles were prepared by laser ablation in liquid. Afterglow nanoparticles were capped with silica using Stber method. A dense silica capping layer was achieved after 4 hours of reaction. Silica-capping of the afterglow nanoparticles improved the particles' afterglow property, which was degraded by nanosizing. Decay curves indicated that initial values of afterglow intensity were increased with silica-capping capacity. Moreover, silica-capping decreased the decay curve constant , which was related to trap parameters. The decrease in the value of resulted in the reduction in the slope of decay curve, and thus the improvement of the afterglow property. We concluded that capping nanoparticles with silica improved the particles' afterglow property by the passivation of surface defects and the prevention of energy transfer to water molecules.

Teacher imitation

Not 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.
