A multidentate polymer microreactor route for green mass fabrication of mesoporous NaYF4 clusters†
Abstract
We report a “multidentate polymer microreactor” method for the creation of secondary structures of colloidal nanocrystals. Using NaYF4:Yb,Er as an example, we demonstrate that the use of sodium polyacrylate (PAAS) as a “multidentate polymer microreactor” allows the controllable growth of primary nanocrystals and induces aggregation of the nanocrystals into well-defined mesoporous clusters.
