Abstract

fetched live from OpenAlex

Abstract A novel optical diffuser based on cellulose nanocrystals (CNCs) embedded in polydimethylsiloxane (PDMS) matrix, or cellulose nanocrystal:polymer (CNP) is reported. By offering simple low‐cost fabrication process as well as compatibility with large‐scale production, the proposed optical diffuser is a better choice for integration into optoelectronic devices for light management compared to other cellulose‐based diffusers due to its physical durability and the lack of requirement for index‐matching between the diffuser and the optoelectronic device thanks to the unique surface properties, mechanical flexibility, and optical transparency offered by PDMS as the matrix material. It is demonstrated that CNCs are an excellent filler material to pair up with PDMS in an optical diffuser providing highly efficient broadband light diffusion in visible and near‐infrared range of light at very low concentrations (≈1 wt%). At its optimized form, a CNP hybrid optical diffuser is capable of achieving very high haze values (up to 85%) while maintaining a high degree of transparency (≈85%) at the same time. As a proof of concept, light management capabilities of CNP hybrid optical diffusers are leveraged to demonstrate their potential for light extraction improvement in organic light‐emitting diodes and light absorption enhancement in thin‐film solar cells.

Full frame distilled prediction

Teacher imitation

Not 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.
