RETRACTION: Structural and Optical Modifications of Indium‐Doped Copper Oxide (CuO) Thin Films Synthesized by Chemical Bath Deposition for Enhanced Photoluminescence

RETRACTION: H. F. Etefa and F. B. Dejene, “Structural and Optical Modifications of Indium-Doped Copper Oxide (CuO) Thin Films Synthesized by Chemical Bath Deposition for Enhanced Photoluminescence,” Nano Select (Early View): e70050, https://doi.org/10.1002/nano.70050. The above article, published online on 04 August 2025 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Lisa Smith; and Wiley-VCH GmbH, Weinheim. The retraction has been agreed upon following an investigation into concerns raised by a third party. Multiple instances of duplication were identified across Figures 3a–3e. Additionally, a discrepancy was noted between the scanning electron microscope model specified in the methodology and the one indicated by the metadata in the SEM images. The editors consider the results and conclusions of this article invalid. The authors did not respond to the concerns raised or our notice of retraction.
