Structural and optical investigations of CdO-Na<sub>2</sub>CO<sub>3</sub>-H<sub>3</sub>BO<sub>3</sub> glasses
Bibliographic record
Abstract
Glasses with composition xCdO-(40-x) Na2CO3-60H3BO3; x = 10, 20, 30 and 40 mol% were prepared by conventional melt-quenching technique and checked by XRD technique for their amorphous nature. An increase in density and refractive index of the samples with an increase in content of CdO has been observed and discussed. The optical absorption spectra of the glasses were recorded in the range 200–1100 nm and was used to find optical mobility gap, Urbach energy, and cut-off wavelength for each sample. The decrease in optical mobility gap with increase in CdO points towards the compactness of the structure with the addition of CdO. FTIR spectroscopy reveals the presence of trigonal and tetrahedral borate units, and the results indicate the conversion of BO3 to BO4 units with the increase in CdO content.

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.
