High response organic ultraviolet photodetectors(UV-PDs) were demonstrated with 4,4’,4’’tris[3-methyl-pheny(phenyl)amino]triphenylamine(m-MTDATA) and two Re(I) complexes,(bathocuproine)Re(CO)3 Cl(Re-BCP) and(bathophenanthroline)Re(CO)3 Cl(Re-Bphen) to act as the electron donor and acceptor,respectively.UV-PDs have the configuration of indium tin oxide(ITO)/m-MTDATA(25nm)/m-MTDATA:Re-complex(25―35nm)/Re-complex(20nm)/LiF(1 nm)/Al(200 nm) with different blend layer thicknesses of 25,30 and 35 nm.The optimized PD based on Re-Bphen offers a corrected-dark photocurrent up to 760 μA/cm2 at 10 V,corresponding to a response of 310 mA/W which is among the best values reported for organic UV-PDs.Excellent electron transport ability makes for such high photo-to-electron conversion.
