Correction for ‘Controlled synthesis of lanthanide-doped Gd2O2S nanocrystals with novel excitation-dependent multicolor emissions’ by Lei Lei, et al., Nanoscale, 2017, 9, 5718–5724.


The authors wish to amend the sections of the manuscript detailed below. These corrections are due to the misleading origin of the excitation bands for Eu/Sm/Dy in lanthanide oxysulfide hosts.

The corrections are as follows:

(1) On page 5718 in the sentence beginning “Considering that Tb3+ and…” the phrase “4f → 5d” should instead read as “4f → 5d or 4f → 4f”.

(2) On page 5721 in the sentence beginning “Taking the F-NYG NCs…” the phrase “4fn → 4fn–15d1” should instead read as “4f → 5d or charge transfer band”

(3) On page 5721 in the sentence beginning “On replacing all Gd3+ ions…” the phrase “the intensity of the 4f → 5d transitions for Tb3+ and Dy3+ in the PLE spectra” should instead read as “the intensity of the 4f → 5d transitions for Tb3+ and O2− → Dy3+ charge transfer for Dy3+ in the PLE spectra”.

(4) On page 5721 in the sentence beginning “However, the color variation…” the phrase “4f → 5d transitions of Tb3+ and Eu3+” should instead read as “4f → 5d transitions of Tb3+ and 4f → 4f transitions of Eu3+

(5) The labels in Fig. 4(a) and Fig. S10(b) should be corrected, as shown in the below corrected figures.1

Fig. 4a PLE spectra of F-NYG:Tb3+ (or Eu3+, Sm3+, and Dy3+).

image file: c7nr90246h-f2.tif
Fig. S10b PLE spectrum of F-NYG: 2%Dy (Y2O2S: 2%Dy).

(6) References 9 and 39 given in the sentence beginning “Multicolor emission could not…” should instead refer to the references listed below (ref. 2 and 3)

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
