NiTe{sub 2} nanoflakes and their self-assembled nanoflake arrays (one-dimensional nanostructures) have been prepared by a single-step hydrothermal method using Ni(CH{sub 3}COO){sub 2}.4H{sub 2}O, Na{sub 2}TeO{sub 3}, glucose, and cetyltrimethylammonium bromide (CTAB). CTAB was found to strongly influence the structure and morphology of the resultant NiTe{sub 2}. Morphological transformations from nanoflakes to self-assembled nanoflake arrays and then to solid smooth nanowires were observed as CTAB concentration was increased in the growth solution. Photoluminescence of the NiTe{sub 2} self-assembled nanoflake arrays was investigated for the first time and the formation mechanism of the NiTe{sub 2} nanostructures is also discussed. - Graphical abstract: NiTe{sub 2} nanoflakes and their self-assembled nanoflake arrays have been prepared by a single-step hydrothermal method using Ni(CH{sub 3}COO){sub 2}.4H{sub 2}O, Na{sub 2}TeO{sub 3}, glucose, and cetyltrimethylammonium bromide (CTAB).
