Abstract
In this paper, we study the temperature- and emission wavelength-dependent time responses of previously reported precursor-driven Eu2+- and Dy3+-doped strontium-aluminate phosphors to create unique luminescent anti-counterfeiting tags suitable for detection with smartphones. A smartphone was used to detect the red–green–blue (RGB) components of the rise and decay time responses of the samples in a temperature range from 0 °C to 100 °C. The RGB color-dependent detection revealed a finer excitation/relaxation kinetics structure of the individual samples, which becomes evident in the decay responses. The results suggest another possibility for multilevel encoding and temperature sensor applications, and provides a foundation for developing a more accurate theoretical model of the energy transitions in phosphorescent materials.

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
