Abstract
A general approach of using the electric field-controllable liquid-crystal orientation to modulate the photoluminescence intensity of quantum dots is presented. Liquid-crystal gel-dispersed quantum dots of CdSe/ZnS were prepared using a cholesteric liquid crystal containing either a self-assembled physical network or a covalently crosslinked polymer. The reversible change in liquid-crystal orientational state in response to an applied voltage changes the internal scattering of the excitation light and thus the excitation of the dispersed quantum dots. This leads to an electrically switchable fluorescence emission of CdSe/ZnS in two different ways: high intensity at field-off and low intensity at field-on state, and vice versa.

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 it
