Embodiment Construction

[0013] Such as figure 1 As shown, an organic photomultiplier detector based on surface plasmons, its structure is: 180nm thick indium tin oxide (ITO) as the anode, 20nm poly(3,4-ethylenedioxythiophene)-polyphenyl Ethylene sulfonic acid (PEDOT:PSS) is used as an anode buffer layer, organic matter P3HT:PC with a mass ratio of 100:1 71 BM is used as the active layer, and the integrated silver nano grating (Ag metal grating) matrix and silver film (Ag film) are used together as the back electrode (cathode) of the battery. The cross-sectional width of a single silver column in the silver nano grating matrix is ​​20 nm The square, the height of a single silver column is 32 nm, and the structure is ITO (180nm) / PEDOT:PSS / (20 nm) / P3HT:PC 71 BM(40nm) / Ag metal grating / Ag film(200nm)). The silver film can be obtained by vacuum evaporation; the silver nano grating matrix can be obtained by laser lithography; and other organic functional layers can be obtained on indium tin oxide by spin ...

Abstract

The invention relates to the field of organic photomultiplier detectors, an organic photomultiplier detector based on surface plasmon polariton uses an indium tin oxide ITO as an anode layer and poly(3, 4-ethylenedioxythiophene)-polystyrene sulfonic acid (PEDOT: PSS) as an anode layer, and uses any one of 3-hexylthiophene P3HT, poly[[9-(1-octylnonyl)-9H-carbazole-2, 7-dibasic]-2, 5-thiophene diyl-2, 1, 3-benzothiadiazole-4, 7-dibasic-2, 5-thienyl diyl (PCDTBT, PSBTBT: PC71BM] as a donor material of an organic active layer, and uses fullerene derivative PCBM as an acceptor material of the organic active layer, the donor material and the acceptor material constitute the organic active layer, and an integrated metal nano-grating matrix and a metal thin film are used as a cathode layer, and the nano-grating matrix is inlaid in the organic active layer.

Description

technical field [0001] The invention relates to the field of organic photomultiplier detectors, in particular to a battery structure that uses a rectangular metal grating array as a cathode and excites surface plasmon polaritons (Surface Plasmon Polaritions Mode) to enhance the light absorption of an active layer. Background technique [0002] Organic photomultiplier detectors have many advantages such as light weight, low cost, wide range of materials, flexibility and bendability, and have attracted extensive attention from researchers in recent years. It uses electron (hole) traps to assist holes (electrons) to form tunneling effects to improve the external quantum efficiency (EQE) value of the detector. However, the response speed of the organic polymer photomultiplier detector is relatively slow, and its ability to collect carriers is poor. Aiming at such problems, researchers have incorporated inorganic nanoparticles or organic dye particles into the active layer of th...
