Characterization and structural studies of vanadium doped lithium–barium–phosphate glasses
Bibliographic record
Abstract
Characterization and structural studies of (P 2 O 5 ) 49.5 (V 2 O 5 ) 0.5 (BaO) x (Li 2 O) 50– x (where x = 0, 5, 10, 15, 20, 25 mol%) glasses are reported. These glasses were prepared using the conventional melt quenching technique. X-ray diffraction and differential scanning calorimetry measurements were performed to confirm their amorphous nature. Infrared spectra of these glasses show absorption peaks in the ranges 1273–1267; 1098–1088; 1008–1018; 899–889; and 795–760 and 506–474 cm –1 corresponding to P=O, P–O – , (P–O–P) S , (P–O–P) AS , and O–P–O group vibrations, respectively. Thermal stability factor (s) has been evaluated using the values of T g and T c . These glasses exhibit high transition temperature (T g ) and high thermal stability factor (s) indicating that they are thermally stable. Refractive index of the glasses lies in the range 1.59–1.49. Electron paramagnetic resonance spectroscopy of V 4+ show characteristic hyperfine split signal arising from the vanadyl group in this glass matrix. The results are discussed by considering the structural modification of the phosphate network.

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.
