Preparation of Photoluminescence Tunable Cu-doped AgInS
Article in RSC advances. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
In this work, high-quality Cu doped AIS and AIS/ZnS NCs have been first synthesized via a surface doping approach. By varying Cu concentrations in doping, Cu doped AIS NCs exhibit a photoluminescence red-shift from around 600 nm to 660 nm with a decrease of quantum yield from around 30% to 20%. After ZnS coating or zinc etching on the Cu doped AIS NCs, Cu doped AIS/ZnS NCs present photoluminescence peaks from around 570 nm to 610 nm and high quantum yields in the range of 50 ~ 60%. Moreover, it is found that Cu doping can prolong the photoluminescence lifetime of NCs, and the average photoluminescence lifetime of Cu doped AIS and AIS/ZnS NCs is in the range of 300 ~ 500 ns. The resultant Cu doped AIS/ZnS NCs were further encapsulated with amphiphilic polymers and used as biocompatible photoluminescent probes in cellular imaging. The cellular imaging study shows that peptide-conjugated probes can specifically target U-87 brain tumor cells and thus they can be applied to the detection of endogenous targets expressed on brain tumor cells.
