Facile synthesis and thermoluminescence properties of nano bio-ceramic β-Ca2P2O7:Dy phosphor irradiated with 75 meV C6+ ion beam
Bibliographic record
Abstract
Abstract Dy 3+ doped β-Ca 2 P 2 O 7 phosphor has been synthesized using wet chemical method. The scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analysis confirmed the formation of β-Ca 2 P 2 O 7 :Dy nano-phosphors. However, photoluminescence (PL) study was carried out to confirm the presence of dopant ion in the host matrix of β-Ca 2 P 2 O 7 :Dy material. Thermoluminescence (TL) glow curves of β-Ca 2 P 2 O 7 were recorded for different concentrations of Dy 3+ after exposure to various fluences of C 6+ ion beam (75 meV). TL sensitivity of β-Ca 2 P 2 O 7 :Dy 3+ (0.1 mol%) phosphor was 3.79 times more than commercially available CaSO 4 :Dy 3+ . TRIM code based on the Monte Carlo simulation was used to calculate the absorbed doses, ion range and main energy loss. Glow curve de-convolution (GCD) method was used to determine the number of TL peaks and their trapping parameters. The wide linear response of β-Ca 2 P 2 O 7 nanoparticles along with high stability of TL glow curve makes this nanomaterial a good candidate for C 6+ ion beam dosimetry.

How this classification was reachedexpand
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.
