▎ 摘  要

NOVELTY - The automotive electronic component has multiple nanowires mounted on a first conductivity type semiconductor base layer, and includes a first conductivity type semiconductor core, an active layer, and a second conductivity type semiconductor layer from inside to outside. A light emitting device has a graphene quantum dot coating layer mounted on one or both of the surface and interior of the nanowire. The light emitting device includes graphene quantum dots having an average size of 100 nm or less. The light emitting device includes graphene quantum dots having a uniform particle size of at least 90% of the total graphene quantum dots. USE - Automotive electronic component such as vehicle display such as instrument panel, audio, and navigation or vehicle lighting (all claimed) such as indoor light or indicator for light amplification using graphene quantum dot. ADVANTAGE - The automotive electrical component includes a stable quantum dot structure having a size of 100 nm or less and a light emitting device having a uniform structure having a total graphene particle size of 90% or more, thus, improving light extraction and light amplification and maximizing reliability. Since the nanowire has such a three-dimensional shape, the light emitting surface area is relatively wide, so that the light efficiency is increased. DESCRIPTION OF DRAWING(S) - The drawing shows a manufacturing process of a graphene quantum dot 3D light emitting device included in an automotive electronic component.
