▎ 摘　　要

NOVELTY - An apparatus has photon sensing layers, consists of graphene, arranged on top of each other and intermediate layer between each adjacent sensing layers. Each intermediate layer prevents respective color component of light from proceeding into the adjacent photon sensing layer. USE - Apparatus for sensing photons used in handheld mobile communication device (claimed). ADVANTAGE - The apparatus has improved color separation, fairly even absorption of photons in the whole visible light spectrum, is manufactured simply, has low material cost, has fast photoresponse, decreases power consumption, and provides more time for data processing. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for sensing photons. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-section of the photon sensing structure. Anti-reflective coating (101) 1st sensing layer (111) 2nd sensing layer (112) 1st reflective coating (121) 2nd reflective coating (122)
