Larquet, Clément; Carriere, David; Nguyen, Anh-Minh; Le, Thi Kim-Chi; Frogneux-Plé, Xavier; Génois, Isabelle; Le Griel, Patrick; Gauzzi, Andrea; Sanchez, Clément; Carenco, Sophie
Alkali cations are required for the colloidal synthesis of Ln2O2S nanoplates in organic solvent. Based on a thorough experimental analysis using various lanthanides and three alkali ions, we challenge the commonly accepted scenario of partial lanthanide substitution by the alkali, which is supposed to favor the sulfide insertion over the…
