Herein, for the first time, we present a novel solution method for controllable synthesis of the overlooked cubic phase CuGeTe nanocrystals. The resulting CuGeTe nanocrystals are of high quality with monodispersed size and uniform shape. Optical characterization demonstrates that CuGeTe nanocrystals have a broad absorption in the visible to near-infrared region. Furthermore, an optoelectronic device based on CuGeTe nanocrystals exhibits excellent stability, reproducibility and responsivity. The novel synthetic route presented here not only can open a new avenue for fabricating CuGeTe nanocrystals, especially at the nanoscale, but also may further expand their applications.
在此，我们首次提出了一种用于可控合成被忽视的立方相CuGeTe纳米晶体的新颖解决方法。所得到的CuGeTe纳米晶体质量高，尺寸单分散且形状均匀。光学表征表明，CuGeTe纳米晶体在可见光到近红外区域具有广泛的吸收。此外，基于CuGeTe纳米晶体的光电器件表现出优异的稳定性、再现性和响应性。这里提出的新颖合成路线不仅可以为制造CuGeTe纳米晶体开辟一条新途径，特别是在纳米尺度上，而且还可能进一步扩展它们的应用。
