1 Retraction to: Journal of Materials Science: Materials in Electronics (2021) 32:2601–261 https://doi.org/10.1007/s10854-020-05028-5

The Editors-in-Chief have retracted this Article. After publication, concerns were raised regarding similarity between the PL data in Fig. 7a of this article and Fig. 12 in [1] for ZnAg15. Additionally, the DRS spectra of CNAg1, CNAg3, CNAg5 and CNAg10 in this article appear to be highly similar in terms of shapes to those of ZnAg5, ZnAg10, ZnAg15 and ZnAg20 in [1]. The Editors-in-Chief therefore no longer have confidence in the presented data.

None of the authors have responded to any correspondence from the publisher about this retraction.
