Erratum to: Front. Mater. Sci. 2019, 13(4): 389‒398 DOI: 10.1007/s11706-019-0480-1 The authors did not realize that the presentations of some TEM images were incorrect. The versions of such figures and the corresponding text should be changed as follows.
Page 393, the paragraph “TEM images in Figs. 2(a) and 2(b) show silica- and gold-decorated NaHoF4:Yb3+,Er3+ NPs with an average size of 20–30 nm and they are well dispersed. Gold NPs of smaller size of 8–10 nm and darker in contrast can be clearly seen to be attached on the surface of the silica shell and the silica coating can be seen at the edge as a line. Figures 2(b) and 2(c) show HRTEM images with the d spacing of gold NPs as 0.238 nm corresponding to the (1 1 1) plane and the d spacing of NaHoF4:Yb3+,Er3+ NPs as 0.316 nm corresponding to the (1 1 0) plane, respectively. This again confirms the presence of gold and single crystalline nature of gold and NaHoF4:Yb3+,Er3+. The SAED pattern in Fig. 2(d) shows gold diffraction rings (2.363 Å) of randomly oriented particles and NaHoF4:Yb3+,Er3+ diffraction rings (2.921 Å) indicating random distribution of NPs.” should read “The TEM image in Fig. 2(a) show silica- and gold-decorated NaHoF4:Yb3+,Er3+ NPs with an average size of 20–30 nm and they are well dispersed.

The SAED patterns in Fig. 2(d) show NaHoF4:Yb3+,Er3+ diffraction rings (2.919, 2.273, 1.796 and 1.689 Å corresponding to (1 0 1), (1 1 1), (0 0 2) and (1 0 2) planes, respectively) indicating random distribution of NPs.”
