Engineering the color rendering index of phosphor-free InGaN/(Al)GaN nanowire white light emitting diodes grown by molecular beam epitaxy
Bibliographic record
Abstract
The functional properties, such as color rendering index (CRI) and correlated color temperature (CCT) of nanowire white light emitting diodes (LEDs), have been studied. The nanowire LEDs can generate broad spectrum white light, and by controlling the growth conditions, it is easy to tailor the spectrum. This is a significant advantage over phosphor converted or nanocrystal based white light sources since it is difficult to modulate the spectrum while maintaining high efficiency using these conventional methods. The authors demonstrated that the InGaN/(Al)GaN dot-in-a-wire heterostructure LEDs can generate high CRI values of 94–98 in both warm and cool white regions. Furthermore, the generated light demonstrates relatively stable CCT, CRI, and Commission Internationale d'Eclairage coordinates at different injection currents.

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.
