Luminomagnetic Silica-Coated Heterodimers of Core/Shell FePt/Fe₃O₄ and CdSe Quantum Dots as Potential Biomedical Sensor

Figure 3

XRD patterns and the respective JCPDS standards (numbers in parentheses) of the (a) magnetic nanoparticles core (FePt/Fe₃O₄) and (b) the HNS after the CdSe formation onto the magnetic core surface (FePt/Fe₃O₄-CdSe) before annealing. Lines correspond to the adjustment of shape profile fitted from Lorentz equation according to the different phases present in the sample, identified by colors.
