Near-infrared photoluminescent flowerlike α-In2Se3 nanostructures from a solvothermal treatment
چکیده انگلیسی


• α-In2Se3 nanostructures were firstly prepared by a facile solvothermal route.
• The flowerlike architectures were composed of two-dimensional nanosheets.
• The products exhibit a strong photoluminescence emission in NIR region.

In this article, we first report a facile solvothermal route, via using green and phosphine-free oleic acid (OA) as the solvent, to synthesize flowerlike α-In2Se3 architectures assembled by two-dimensional (2D) nanosheets. This synthetic approach requires no precursor pre-synthesis or toxic compounds. The formation mechanism of the flowerlike α-In2Se3 structures was discussed in detail. This simple synthetic route may provide a new possibility in the challenge of preparing other metal selenides with nanostructures. These as-prepared flowerlike α-In2Se3 nanostructures exhibit a strong room-temperature photoluminescence emission in NIR region excited at 320 nm, which might offer a kind of novel alternative functional nanomaterials in the field of photovoltaic cells, bioimaging, and biolabeling.
