Role of iodine in the solubility of Tm^3+ ions in As_2S_3 glasses
Bibliographic record
Abstract
The effect of iodine (I2) on the photoluminescence properties of Tm3+ ions in the As2S3 matrix was investigated. Results showed three strong emission bands at 1.22 µm (3H5→3H6), 1.46 µm (3H4→3F4) and 1.82 µm (3F4→3H6) under the excitation wavelength of 800 nm, indicating that I2 enables the solubility of Tm3+ ions in As2S3 glasses. The concentration ratio of I2 and Tm3+ were optimized and it revealed that the increasing of the concentration of I2 of 4 times in the glass increases the solubility of Tm ions three times. The effects of the I2 on the fundamental glass properties, including optical, thermal and structural characteristics, were explored as well.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
