Tuning photoluminescence in Gd
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 2 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
The utilization of luminescent phosphors in barcode technology can enhance the security feature. Using NaOH as a reducing agent, we have prepared Gd2O3:Eu3+/Er3+ for luminescent phosphor. The cubic structure of Gd2O3 phosphor is confirmed by the structural analysis conducted using XRD. Dopant Eu and Er induce lattice contraction and expansion in the host lattice, respectively. Based on SEM analysis, porous and irregular particles with an average size of 401 nm were observed. In Tem analysis of prepared phosphor have some particle are in spherical in shape. The formation of Gd2O3 was confirmed by Gd-O band stretching as shown in the FTIR analysis. The emission in the red and green regions is emitted by Gd2O3:Eu3+ and Gd2O3:Er3+, respectively. The emission peaks of Gd2O3:Eu3+/Er3+ are observed at 524 nm, 539 nm, 549 nm, 563 nm, 593 nm, 612 nm, and 629 nm when it is triggered by 363 nm, with a maximum energy transfer efficiency of 95.93%. Enhancing the security of barcodes can be achieved through the use of color-tunable Gd2O3:Eu3+/Er3+ phosphor. Gd2O3:Er3+ (1.5 mol%) is a prominent candidate for LED bulbs due to its CCT (5765 K).
