摘要

Highly crystalline NaYF ₄:Ln ³ (Ln=Yb, Er, Tm) crystals with honeycomb structure were successfully synthesized for the first time by using a mixed NaClKCl flux cooling method at a holding temperature of 800 °C for 2 h in air. The results indicated that the crystals of NaYF ₄:Ln ³ belonged to hexagonal system and three-dimensional open pores had an average diameter of 1 μm interconnected with each other. Upon 980 nm laser diode excitation, yellow green and sky blue upconversion fluorescences of β-NaYF ₄:20%Yb ³, 2%Er ³ crystals and β-NaYF ₄:20%Yb ³, 0.5%Tm ³ crystals, which was caused by two- or three-photon upconversion processes, was observed clearly.
