Microwave-assisted synthesis of NaMnF3 particles with tuneable morphologies

Abstract

Here, the synthesis of sub-micron MMnF₃ (M = Na or K) particles by a rapid microwave-assisted approach is reported. Adjustment of the Na⁺-to-Mn²⁺ ratio in the reaction mixture yielded tuneable morphologies, i.e., rods, ribbons, and plates. Relaxometric results indicated that poly(acrylic acid)-capped MMnF₃ particles exhibited characteristic magnetic properties, which endows them with potential T₁-weighted contrast agent capabilities.
