Comparative investigation of structural, photoluminescence, and magnetic characteristics of MxSn1−xOy nanocomposites

Structural, optical, and dielectric properties of hydrothermally synthesized SnO2 nanoparticles, Cu/SnO2, and Fe/SnO2 nanocomposites

“…It is generally observed that there is no impurity, and most of the diffraction peaks suggest more stoichiometric metal oxide composites and confirm the formation of Cu/SnO 2 and Fe/SnO 2 composites. It was deduced that Cu is far more reactive and well dissolved in SnO 2 than Fe which agrees with other work [41]. XRD patterns of SnO 2 exhibit several sharp diffraction peaks confirming the high crystallinity.…”

“…SnO 2 nanoparticles as well as SnO 2 -50 at.% Cu (Cu/SnO 2 ), and SnO 2 − 50 at.% Fe (Fe/SnO 2 ) nanocomposites were fabricated by the hydrothermal approach as shown in detail elsewhere [5,41]. An appropriate quantity of metal stoichiometric chlorides (SnCl 2 .H 2 O, and CuCl 2 or FeCl 3 ) was weighted according to their atomic percentage ratios, and dispersed in 20 ml of distilled water with the agitation at RT for ½ h. The desired nanocomposite was obtained by adding drops of 5.25 M NaOH solution to the chloride solution while the mixture constantly stirring.…”

“…Permanent electric dipoles emerge as a result of hopping between Sn 4+ and M 3+ ions when SnO 2 is replaced by M ions [15,20,[35][36][37]40]. Recently, structural, morphology, Fourier-transform infrared spectroscopy (FTIR), photoluminescence (PL), and magnetic measurements of M x Sn 1-x O y nanocomposites with various x (0 and 0.5) and M (Cu, Fe, Al, Mn, and Ni) have been investigated [41]. The residual stress, Debye temperature, and Young's modulus of SnO 2 were increased by M addition.…”
