NaYF<sup>4</sup>:Er<sup>3+</sup>,Yb<sup>3+</sup>crystals were prepared by simple synthetic method. Under 980nm laser excitation, 408nm, 539nm and 655nm upconversion signals were recorded. Laser power and signal intensities of the upconverted emissions were obtained to understand the upconversion mechanisms.
