The Editor-in-Chief has retracted this article due to an overlap of content from multiple previously published sources and concerns regarding the data presented in this article. Specifically:

• The data of the micro strain in Table 2 were not correlated with the data in Fig. 2.

• The average volume reported in Table 8 was not correlated with Table 2.

• The SEM images in Fig. 4 are of Zn_0.9655Ba_0.0345Al_1.9655O₄:Eu_0.0345 phosphor and not Zn_0.95Al_1.95O₄:Eu_0.05Sr_0.05 phosphor as claimed in the article.

• In Table 2 the XRD values are similar to the XRD values in Table 3 of a previously published article [1].

• The reported peak angles, FWHM, Crystalline sizes and the d-spacing are the same as those that have been presented in a previously published article [2].

• Fig. 7D appears to overlap with Fig. 7D from a previously published article [1].

• In Fig. 8 the FTIR image of Zn_0.95Eu_0.05Al_1.95Sr_0.05O₄ phosphor is similar to the FTIR image of Fig. 6 in a previously published article [2].

• In Fig. 9 the Raman spectrum is similar to Fig. 7 of a previously published article [2].

• Fig. 10 appears to be highly similar to Fig. 10 in a previously published article [3].

• Fig. 17B and C appear to overlap with Fig. 15A and D from a previously published article [4].

The Editor-in-Chief has therefore lost confidence in the reliability and integrity of the work presented in this article.
