In this paper, well-dispersed α-NaYF₄ nanocubes were synthesized with a polyol method. The influence of molar ratio of F⁻/Y³⁺/Na⁺ and type of polyol on the phase and morphology of the as-prepared NaYF₄ samples was examined. Formation process of these α-NaYF₄ nanocubes was traced via time-dependent experiments. Photoluminescence measurements demonstrated the as-prepared nanocubes are good up- and down-conversion luminescent host materials.
