▎ 摘　　要

NOVELTY - A dual-band graphene detection chip comprises a silicon layer (S1), a quantum dot-reinforced graphene layer (G1), an epoxy resin adhesive layer (E1), a silicon layer (S2), a quantum dot-reinforced graphene layer (G2) and an epoxy resin adhesive layer (E2), which are laminated in sequence from bottom to top. The quantum dot-enhanced graphene layer (G1) is used for detecting medium-wave infrared light, long-wave infrared light or very long-wave infrared light. The quantum dot-enhanced graphene layer (G2) is used for detecting visible light, short-wave infrared light or medium-wave infrared light. USE - Dual-band graphene chip is used in detection device (claimed). ADVANTAGE - The dual-band graphene chip has excellent detection rate and response speed. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a dual-band graphene detection device; and (2) preparation of the dual-band graphene detection chip.
