Abstract
The present invention discloses a light-diffusion quantum dot nanostructure and an LED component having the same. The quantum dot nanostructure comprises an optical core, an organic ligand layer, a hydrophobic layer, an inorganic encapsulation layer, and a multi-layered water vapor barrier layer. In the present invention, the multi-layered water vapor barrier layer is particularly designed to an onion skin-like structure, so as to facilitate photoluminescence rays radiated from the optical core can emit out of the barrier layer via voids or pores of the onion skin-like structure, such that the uniformity of the spatial light output distribution of the LED component having the quantum dot nanostructures can be obviously enhanced. On the other hand, because the multi-layered water vapor barrier layer can also improve the dispersibility of the light-diffusion quantum dot nanostructures in a colloidal encapsulation of the LED component, the luminous intensity of the LED component is therefore increased.
