Characterization of optical and photoelectric properties of a new boron-based organic semiconductor in the near-infrared regions
Optical and photoelectric properties, especially in near infrared ray (NIR) region, of dibenzopyrromethane boron chelate derivatives (BODIPY-Ph) were investigated. The BODIPY-Ph vacuum-evaporated thin films showed broad-band absorption in the wavelength rang of 600-1000 nm with the peak at 770 nm. The NIR organic photodetector (OPD) fabricated with BODIPY-Ph exhibited photocurrent of 2.18×10 -3 mA/cm 2 at 1.5 V under 800 nm irradiation. This value was about 700 times higher than dark current at the same voltage. These results suggest that BODIPY-Ph is one of the promising candidates for use in NIR-OPDs.
