Development of two-dimensional nanosheet for light emitting device

纳米片是一种厚度为1纳米的二维材料。由于厚度与分子的大小相对应，它显示出各种物理性质，如块状材料不表现出的量子尺寸效应。纳米片材的研究才刚刚开始，因此，人们期待着一种新的物理性质和功能。在本研究中，我们重点研究了纳米薄片的光学和/或光转换特性。制备了纳米片pn结、氮掺杂氧化物纳米片、p型纳米片和不猝灭的发光纳米片。

Nanosheet is a two-dimensional material with a thickness of 1 nm. Since the thickness corresponds to the size of a molecule, it shows various physical properties such as a quantum size effect that a bulk material does not show. The study of nanosheet has just begun, and therefore, a new physical property and function are expected. In this study, we focused on the optical and/or light conversion properties of nanosheet. Preparation of nanosheet pn-junction, nitrogen-doped oxide nanosheet, p-type nanosheet, and luminescent nanosheet without quenching were performed.
