Abstract

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 → 4f^n–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⁺).

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.
