Thin Film Photodetectors Based on Zinc Oxide Nanoinks
Bibliographic record
Abstract
We report on the fabrication and characterization of ZnO thin film photodetectors using planetary ball-milled nanoparticle suspensions (nanoinks). Milling parameters, speed and time, were varied between 200 rpm and 1000 rpm, and 10 and 60 minutes, respectively to produce suspensions with particles below 100 nm in diameter. The resulting PBM nanoinks were used to create ZnO thin films whose photoconductance was measured under broadband UV/visible illumination. Thin film ZnO photodetector devices showed strong response upon light exposure with up to an order of magnitude increase in photocurrent compared to baseline (dark) for the conditions studied. This work demonstrates the use of low-cost PBM nanoinks for the active materials in solution-processed thin film photodetectors based on ZnO and allows film properties to be tailored and optimized for different applications in a straightforward manner by adjusting grinding conditions.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
