The treatment effect on the agglomeration of DyF3 nanoparticles using 1H NMR
The agglomeration processes of DyF3 nanoparticles without and with different types of treatment were studied by the zeta-potential and time-domain 1H NMR measurements. 1H transverse nuclear magnetization decay curves were recorded in a 3.65 T magnetic field for all samples over time. T2 distributions were analyzed using the inverse Laplace transform based on regularized inverse Laplace transformation (RILT) algorithm. The concentration dependence (0.05 −1 mM) of the spin-spin relaxation rate was measured for DyF3 nanoparticles treated hydrothermally in an autoclave. The influence of thermal treatment methods on the agglomeration rate of DyF3 nanoparticles has been discussed. The results demonstrate that of autoclave processing of the colloidal solution offers advantages over microwave treatment. Furthermore, theoretical estimates of nanoparticle agglomeration rates were performed for DyF3 samples subjected to different treatments. Finally, toxicity studies revealed that DyF₃ nanoparticles exhibit negligible toxicity at concentrations up to 1 mM.
