Abstract

fetched live from OpenAlex

In this work, we report results of lead sulfide (PbS) quantum dots (QDs) luminescence spectra evolution during the QDs spread process around the core of silica micro-structured (MS) fibers. These QDs are excited, via evanescent field effect, with a 532nm or 785nm laser guided by the MS-fiber cores. The PbS-core QDs of different sizes (originally immersed in Toluene) with emission bands around 877 nm (PbS877), 1160 nm (PbS1160) and 1474 nm (PbS1474) were inserted inside the silica MS-fiber structure by using an N2 gas pressure system. The broadband luminescence spectra varying from around 1000 nm to 1600 nm were obtained by using QDs mixtures impregnated around MS-fiber core surfaces. This QDs spread technique and the PbS QDs broadband luminescence spectra results could have potential applications in optical amplifier,sensor and nonlinear optical fiber loop mirror devices.

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.
