Les caractéristiques des photodétecteurs organiques (OPD) sensibles au violet utilisant des matériaux polyalkylfluorène et triplet ont été étudiées respectivement comme matériau hôte et dopant. Pour la couche de photoabsorption, du poly(9,9-dioctylfluorène) [PFO] et un complexe d'iridium phosphorescent (Iridium (III) bis(2-(4,6-difluorophényl)pyridineto-N,C2) [FIrpic] ou Iridium (III) bis(2-(2'-benzothienyl)pyridineto-N,C3')(acétyl-acétonate) [(btp)2Ir (acac)]) ont été utilisés respectivement comme matériau hôte et dopant. FOP : (btp)2L'appareil Ir(acac) a montré moins de photocourant que l'appareil PFO car (btp)2Ir(acac) améliore la recombinaison des porteurs photogénérés dans la couche de photoabsorption. D'autre part, le dispositif PFO : FIrpic a montré un photocourant plus important que le dispositif PFO en raison du transfert d'énergie triplet de FIrpic au PFO. Une fréquence de coupure de 20 MHz a été observée à l'aide d'un éclairage laser violet modulé sinusoïdalement sous une polarisation inverse de 8 V.

Abstract: The characteristics of violet-sensitive organic photodetectors (OPDs) utilizing polyalkylfluorene and triplet materials have been studied as a host and a dopant material, respectively. For the photo absorption layer, poly(9,9-dioctylfluorene) [PFO] and a phosphorescent iridium complex (Iridium (III) bis(2-(4,6-difluorophenyl)pyridinato-N,C2) [FIrpic] or Iridium (III) bis(2-(2'-benzothienyl)pyridinato-N,C3')(acetyl-acetonate) [(btp)2Ir(acac)]) were used as a host and a dopant material, respectively. PFO: (btp)2Ir(acac) device showed less photocurrent than PFO device because (btp)2Ir(acac) enhances recombination of the photo generated carriers in the photo absorption layer. On the other hand, PFO : FIrpic device showed larger photocurrent than PFO device due to triplet energy transfer from FIrpic to PFO. A cutoff frequency of 20 MHz was observed using a sinusoidal modulated violet laser light illumination under the reverse bias of 8 V.
