    Sm3+-doped magnetic nanoparticles (NPs) were prepared via microwave-assisted polyol synthesis in ethylene glycol, poly(ethylene glycol) and mixed ethylene glycol - poly(ethylene glycol) solutions. In present work, the effects of organic solvent composition on particle size, particle size distribution, extent of agglomeration, and samarium content in prepared NPs were studied. The synthesized NPs were characterized by several techniques as follows: X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetry (TGA) and X-Ray fluorescence (XRF) analysis. XRD and TEM results showed formation of ~6.0 - 17.9 nm NPs having different microstructure characteristics (average particle size, particle size distribution, and agglomeration
