Retraction of: Scientific Reports https://doi.org/10.1038/srep46603, published online 24 April 2017

The Editors have retracted this Article.

Figure 1 appears to be in part identical to Figure 1 of another published article1, despite the materials and methods describing how the nanorods were grown differently. The fluorescent spectrum presented in Figure 6 also appears to be identical to Figure 2B of1, and Figure 2 of2. The image for Figure 2C appears to have been duplicated in Figure 7C. This image also appears to have been published as Figure 3D in2, and Figure 12C of3. The images for Figure 7B and 7D appear to have been published, respectively, as Figure 12B and 12D in3. The Editors therefore no longer have confidence in the validity of the data and the conclusions drawn.

M. Waseem Akram and Zhiming M. Wang agree with the retraction and its wording. Muhammad Fakhar-e-Alam, Seemab Iqbal, K. S. Alimgeer, M. Atif, and M. Willander did not respond to the correspondence about retraction. The Editors were not able to establish current contact details for K. Sultana.
