Abstract

We, the named authors, hereby wholly retract this CrystEngComm article due to data fabrication in Fig. 4 and 6. One of the spectra in Fig. 4, corresponding to nanocrystals of varying Sn/Ge content, has been copied and shifted within the figure: the purple spectrum (x = 1) is the copy of the black spectrum (x = 0). One of the plots in Fig. 6b, corresponding to nanocrystals of varying Sn/Ge content, has been copied and shifted: the blue curve (x = 0.3) is the copy of the green curve (x = 0.7).

An investigation by Dr Yongping Lei (Professor and Chairman of College Council of the College of Materials Science and Engineering, Beijing University of Technology, China) determined that Kai Zong was responsible for these instances of data fabrication. Hao Wang, as his tutor and also corresponding author, is responsible for the duty of supervision and management. Other co-authors accept joint responsibility for the preparation of article. Please allow us to sincerely apologise to all readers and the Editorial Office.

Signed: Kai Zhong, Si Heng Lu, Hao Wang, Yu Xiu Sun, Hui Juan Zheng, Jing Bing Liu, Hui Yan, 25 November 2013.

This retraction is endorsed by Jamie Humphrey, Editor, CrystEngComm. Retraction published 13 December 2013.
