Photonic crystal with a defect layer of silicon containing polymer nanocomposites as radiation detector.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This paper presents a photonic crystal-based gamma radiation detector featuring a defect layer of silicon embedded with polymer nanocomposites. The transfer matrix method is utilized as a computational tool to evaluate the transmittance properties of the proposed detector. The study investigates the effects of cell count and porosity on the detector's performance. The model can accurately and simultaneously distinguish between different gamma radiation doses by observing changes in the refractive index of the active layer. The detector demonstrates high sensitivity, with 0.804 nm/Gy for doses ranging from 0 to 100 Gy and 0.225 nm/Gy for doses between 100 and 200 Gy. The proposed model, incorporating porous silicon and ethylene oxide polymer nanocomposites, exhibits exceptional performance as a gamma radiation sensor.
