Optical Band Gap of Nanocompsoite MEH-PPV:TiO[sub 2] Thin Film
Bibliographic record
Abstract
In our work, the white pigment TiO2 powder was first annealed at 450° C before mixing it to the polymer solution to ensure that the TiO2 was in its anatase phase. The 50 mg MEH‐PPV polymer was dissolved in tetrahydrofuran (THF) with a concentration of 1:1. The composite materials were prepared by adding appropriate amounts of TiO2 powder 5, 10, 15 and 20 wt% into the polymer solution to make various ratios of TiO2 powder/polymer composites. The optical band gap and surface morphology of nanocomposite conjugated polymer MEH‐PPV:TiO2 were investigated. We observed that as the concentration of TiO2 increase from 0, 5, 10, 15 and 20 wt%, the optical band gap decrease slightly from 4.20, 4.16, 4.14, 4.13 and 4.12 eV respectively. Also we observed that the dispersity of the TiO2 powder was not uniform as the concentration of the TiO2 powder increase from 0 to 20 wt%.

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.
