In the present invention, a light diffusion quantum dot nanostructure composed of an optical core, an organic ligand layer, a hydrophobic layer, an inorganic encapsulation layer, and a water-oxygen barrier layer of a multilayer structure is applied put forward. Moreover, the present invention also proposes a new type of light-emitting diode chip with this light-diffusing quantum dot nanostructure. In particular, the water-oxygen barrier layer of the multi-layer structure is designed as a kind of onion skin structure, so that the light-excited fluorescent light emitted by the optical core can smoothly emit light through the gaps in the onion skin structure, so that the light emission can be improved. The luminous uniformity of the polar body wafer. On the other hand, the onion-skin-like multi-layer water-oxygen barrier layer can also enhance the dispersion of the light diffusion quantum dot nanostructure in the encapsulating colloid in the light-emitting diode chip, thereby effectively improving the light-emitting diode The luminous intensity of the wafer. |
