The synthesized encapsulated material was characterized by elemental analysis, FTIR, UV-Visible spectroscopy, TGA, single crystal and powder X-ray diffraction and photoluminescence spectroscopy. The results showed that the synthesized composite, RhB-Zn-MOF could be used as an efficient probe for the selective sensing of Cr(VI) in the presence of Cr(III) as well as other metal ions.eninfo:eu-repo/semantics/closedAccessZn-MOFRhodamine BDye encapsulationCr(VI)Photo-luminescenceArticle31010.1016/j.saa.2024.123899382665982-s2.0-85183622784Q1WOS:001171468900001Q1
