EFFECT OF SILVER NANOPARTICLE ADDITION ON THE STRUCTURE AND CHARACTERISTICS OF RADIO-PHOTOLUMINESCENCE GLASS DOSIMETER
Bibliographic record
Abstract
A series of silver-activated phosphate glass was prepared by melt quenching method. The effect of silver nanoparticle addition on the phosphate glass microstructure, composition and chemical characteristics was investigated using x-ray diffraction, fourier transform infrared and photoluminescence spectroscopy. Other physical property such as density was also evaluated. The density increased when the amount of silver ions were increased, due to the enhanced formation of non-bridging oxygen. In this study, we discuss the emission mechanism of two radio-photoluminescence peaks at 460 nm and 620 nm, where the electrons and holes produced by -irradiation a re-trapped by Ag + ions to produce Ag 0 and Ag 2+ ions respectively, when the Ag + -doped phosphate glass is exposed to -ray. We proposed that an emission mechanism of 460 and 620 nm radio-photoluminescence peaks with these Ag 2+ and Ag 0 ions. Furthermore, a correlation between the investigated properties and glass composition is discussed.

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.
