Our lives have been shaped by our ability to create and manipulate new materials, with the ages of civilizations being marked with our mastery of a particular material class. Yet, only recently have there been forums for the exchange of knowledge about the chemistry of new materials. In his opening editorial to Chemistry of Materials in 1989, then Editor-in-Chief Leonard Interrante articulated a vision

Due to an unintended oversight, this Reply to Comment was published online on October 26, 2020, prior to the Comment also being available online. The Comment was published online on November 6, 2020. In a recent Comment, Yu et al. proposed that the emission observed by us in Mn4+:Na4Mg(WO4)3 phosphors stems from Mn2+ rather than Mn4+. However, that claim is not supported by the experimental data the

Figure 11a on page 3312 in the paper: The authors regret that the Figure 11a of the published article was incorrect. In Figure 11a, there is a TEM image (inset) that is incorrect and redundant, and now we delete it. The corrected Figure 11a is shown below. The other experiments in this paper were not affected by this issue. In addition, the data analysis and conclusions in this paper are not affected

Regrettably, the graph of relative brightness in Figure 6A was published with a labeling error. The originally published graph has a horizontal axis that logarithmically spans nine decades but is labeled from 102 to 109 M–1 cm–1. The correct labeling is from 102 to 1011 M–1 cm–1. A corrected Figure 6 is shown on the next page. Figure 6. Blueprint for the design of molecular and cellular assay platforms
