Abstract

Monodisperse β-NaYF₄:Ln³⁺ (Ln = Yb/Er, Yb/Tm) single micro/nanocrystals were first one-pot fabricated at 50 °C through a novel synthetic route containing two pivotal processes: (a) synthesis of a β-NaYF₄ {0001} unit layer through a novel style of ion-exchange from Y₂(OH)₅NO₃·nH₂O (LYH) and (b) the subsequent oriented-assembly process.
