A Photoelectric Property of Merocyanine LB Film Cell Utilizing Surface Plasmon Polariton Excitation

摘要

Short-circuit photocurrents (I_SC) utilizing sur- face plasmon polariton (SPP) excitation were investigated for the merocyanine (MC) LB film photoelectric device. The device has a prism/MgF_2/Al/MC LB film/Ag structure. In the attenu- ated total reflection (ATR) configuration, SPPs were resonantly excited at the interfaces between MgF_2 and Al(MgF_2/Al) and between Ag and air (Ag/air). The thickness and the dielectric constants of the layers were evaluated from the ATR measure- ments.
