▎ 摘　　要

NOVELTY - The device has a main body provided with a substrate (10), a graphene layer (20), a structure layer (30) and a fluorescent molecular layer (40). The structure layer is provided with multiple periodically arranged structure portions. Each structure portion is connected with a first nanorod (34) and a second nanorod (34). A first magnetostrictive material portion (35) is arranged on a side of the first nanorod away from the second nanorod. A second magnetostrictive material portion is arranged on another side of the second nanorod far away from the first nanorod. A fluorescent molecular layer is coated on a surface of a side of the structure layer and the graphene layer far away from the substrate. USE - Device for controlling circular polarization luminescence of a circular polarization light emitting device. ADVANTAGE - The graphene layer is fixed on a lower side of the structure layer so as tp aggregate strong chiral field caused by an interlayer coupling, thus improving luminous intensity. The device is simple in structure, and has wide application range. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a device for controlling circular polarization luminescence. 10Substrate 20Graphene layer 30Structure layer 31First nanowire 32Second nanowire 33First nanorod 34Second nanorod 35First magnetostrictive material portion 40Fluorescent molecular layer
