Morphology controlled synthesis of Fe³⁺-doped upconversion nanomaterials.

ABSTRACT: This work details the synthesis of paramagnetic upconversion nanoparticles doped with Fe³⁺ in various morphologies via the thermal decomposition method, followed by comprehensive characterization of their structures, optical properties and magnetism using diverse analytical techniques. Our findings demonstrate that by precisely modulating the ratio of oleic acid to octadecene in the solvent, one can successfully obtain hexagonal nanodiscs with a consistent and well-defined morphology. Further adjustments in the oleic acid to octadecene ratio, coupled with fine-tuning of the Na⁺/F^- ratio, led to the production of small-sized nanorods with uniform morphology. Significantly, all Fe³⁺-doped nanoparticles displayed pronounced paramagnetism, wit
