![عکس صفحه اول مقاله: Synthesis of ultrathin wurtzite ZnSe nanosheets Synthesis of ultrathin wurtzite ZnSe nanosheets](/preview/png/1645727.png)
• 1.4-nm-thick ZnSe nanosheets with wurtzite structure are chemically synthesized.
• The crystallographic direction along the thickness is determined to be [11–20].
• Absorption peaks are significantly blue-shifted compared to those of bulk materials.
• Interaction between the nanosheets can be modified by using different surfactants.
We demonstrate a facile chemical synthesis of 1.4-nm-thick zinc selenide (ZnSe) nanosheets with wurtzite structure. Owing to the quantum confinement arising from the ultra-thinness, absorption peaks are significantly blue-shifted compared to those of bulk materials. The narrow width of the peaks (<10 nm) indicates that thickness of the nanosheets is highly uniform. Successful synthesis of ZnSe nanosheets implies that the same chemical route may be further extended to synthesize various other non-layered materials in the form of two-dimensional nanosheet.
