Název v původním jazyce

Europium(III) and Gadolinium(III) co-doped nanohydroxyapatite with enhanced photoluminescence as potential multimodal bioimaging agent

Popis výsledku v původním jazyce

The advancement of bioimaging and theranostics necessitates the development of highly biocompatible multifunctional agents. Here, we introduce a potential multimodal agent based on nanosized hydroxyapatite (HAp) codoped with europium(III) and gadolinium(III) (Eu(3+) and Gd(3+)) ions. The study presents a detailed characterization of the HAp:Eu(3+)/Gd(3+) nanoparticles synthesized via the co-precipitation method. The structure and morphology were analyzed using X-ray powder diffraction (XRPD), transmission electron microscopy (TEM), and Fourier transform infrared (FT-IR) spectroscopy. The study of spectroscopic properties (emission, excitation, emission kinetics) as a function of optically active ions was carried out. Moreover, various dopant ratio combinations were studied to optimize the optical and magnetic properties. HAp:Eu(3+)/Gd(3+) demonstrates tunable PL intensity with different concentrations of Eu(3+) and Gd(3+) ions and increased magnetization with higher doping with Gd(3+) ions. Furthermore, co-doping with Gd(3+) ions results in an enhancement of Eu(3+) emission intensity, rendering HAp:Eu(3+)/Gd(3+) a potentially promising candidate for bioimaging applications.
