Abstract
High Resolution Image Download MS PowerPoint Slide Recent developments in room-temperature phosphorescence (RTP) from biobased polymers have shown great promise in realizing sustainable RTP systems. Here, we introduce an efficient “top-down” method to achieve RTP biofibers using bamboo following partial delignification (B-fibers). The photophysical characterization combined with structural, surface, and chemical inquiries along with DFT calculations revealed the fundamental reasons for RTP, associated with the interactions between cellulose, hemicelluloses, and the residual lignin. Multiple emissive oxygen-containing clusters and aromatic chromophores in the B-fibers were shown to be RTP-active with a lifetime of 294.9 ms. The RTP emission of the B-fibers was found to be sensitive to temperature, excitation, and humidity. Moreover, when combined with a water-soluble fluorescent dye, red afterglow emission was demonstrated under the effect of energy transfer. Following these results, we synthesized functional luminescent materials (paper, films, textiles, and aerogels), proposed herein as practical, sustainable, and compostable choices for photoexcitation in the visible range.

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
