Abstract

High-quality hexagonal nanocrystals (β-NaYF4:Yb3+,Er3+) were prepared through one-pot mild solvothermal synthesis. The crystal structure of NaYF4:Yb3+,Er3+ can be controlled by changing the molar ratio of phosphate to Ln3+ (Ln3+ represents the total amount of Y3+ and the doped rare earth elements such as Yb3+, Er3+).
