Fabrication of Hydrophilic Gadolinium Hydroxide Sheets via A Gadolinium-Based Precipitation Reaction

In this work, we report a facile strategy for synthesizing hydrophilic Gd(OH) 3 sheets via a Gd-based interfacial precipitation reaction at the interface of organosilane-modified Gd 2 O 3 nanoparticles and a cation exchange resin. This strategy, independent of the specific organosilane used, produces two-dimensional sheets with a distinct lamellar structure and excellent aqueous dispersibility. Characterization confirms the formation of Gd(OH) 3 sheets with promising fluorescent and magnetic properties.
