Abstract
Disclosed are an optoelectronic device and a preparation method thereof. The optoelectronic device includes a first semiconductor layer, an active layer, and a second semiconductor layer stacked in sequence. The conductivity type of the first semiconductor layer is opposite to that of the second semiconductor layer, and the second semiconductor layer is provided with a layer of nano-diamond structure, and the nano-diamond structure has the same conductivity type as the second semiconductor layer. The method for preparing the optoelectronic device is used to make the optoelectronic device. In the present application, by providing a layer of nano-diamond structure in the second semiconductor layer, the absorption of UV light emitted by the active layer can be effectively avoided, and the beneficial effect of greatly improving the light extraction efficiency of the UV LED can be achieved.
