The size of them is about 600 nm 400 nm (side length thickness). The obtained sample was divided into two parts and one of them was annealed in nitrogen at 300 C for 2 hours. The crystal structure of the -NaYF4: Yb3+  Er3+ hexagonal sub-microplates before and after annealing treatment is hexagonal phase. Under the excitation of 980 nm diode laser  the upconversion luminescence intensity the sample after annealing is much stronger than that of the sample without annealing treatment. High temperature annealing process improved the crystallization of the sample  resulting in the decrease of the nonradiative relaxation and the enhancement of the upconversion luminescence.

Upconversion luminescence can be observed in all of the samples at room temperature. Fixed the Er3+ concentration with 1 mol% unchanged  the effect of the Yb3+ concentration on the upconversion luminescence of NaYF4: Yb3+  Er3+ samples were studied when the doped Yb3+ concentrations were 0 mol%  1 mol%  2 mol%  5 mol%  10 mol% and 20 mol%  respectively. As increasing the Yb 3+ concentration  the total intensity of the upconversion luminescence of the samples is increasing while the ratio of red to green emission increases firstly and then decreases. The maximum ratio value is 22.1 when the Yb3+ concentration is 10 mol%. It is found that the cross relaxation and cooperative sensitization effect are the reasons for the phenomenon above.
