Cathodoluminescence of Sr<sub>2</sub>B<sub>5</sub>O<sub>9</sub>Cl thin films doped with Tm<sup>3+</sup>, Tb<sup>3+</sup>and Mn<sup>2+</sup>
Bibliographic record
Abstract
Thin-film phosphors of Sr2B5O9Cl doped separately with Tm3+, Tb3+ and Mn2+ were deposited by spray pyrolysis of aqueous solutions. Because these phosphor films were activated at 600 °C, they are suitable for use on glass substrates. The films containing Tm3+, Tb3+ and Mn2+ exhibited blue, green and yellow cathodoluminescence (CL), respectively. The chromaticity coordinates, dominant wavelength and purity were determined for each phosphor. Films deposited on aluminosilicate ceramic plates exhibited enhanced CL intensity compared to those on glass plates. The CL luminance and efficiency of each phosphor depended on the electron beam voltage and current density. Saturation effects were observed as the current density increased.

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.
