The structure of HRP was characterized using spectroscopic techniques. The optical sensor properties of HRP for metal ions were investigated using UV-Vis and Fluorescence spectroscopy. It was determined that HRP is a selective sensor with colorimetric and fluorescent properties for Fe3+ ions. Limit of detection (LOD) of HRP was determined as 6.94 x 10(-9) M using fluorescence intensities in the presence of different concentrations of Fe3+ ions. It was determined that HRP-Fe3+ complex has high quantum yield and excellent photostability.eninfo:eu-repo/semantics/closedAccessFluorescentiron(III)phosphazenerhodaminesensorArticle194322122810.1080/10426507.2018.1539491Q4WOS:0004650072000052-s2.0-85058994903Q3
