Abstract
A photodetector was prepared by depositing PEDOTPSS [poly(3,4-ethylenedioxythiophene) polystyrene sulfonate] and TPD polymer (p-TPD) [N,N′-bis(3-methylphenyl)-N,N′-diphenylbenzidine] on porous silicon (PSi) substrates with a spin coating technique. The value of the response time (4.419 s) of the manufactured PS/PEDOT : PSS/TPD detector (by illuminating the sample with a 250 W/cm2 tungsten lamp) was measured in second’s scale. The detection was 3.9 × 108 W−1, specificity—2.3 × 108 W−1 Hz1/2 cm and optical response—8.85 × 10−3 A/W. The incorporation of AgO nanoparticles with a TPD polymer improved the detection to 80.06 × 108 W−1, specificity − to 46.4 × 108 W−1 Hz1/2 cm, optical response—to 2.01 A/W, and detector response time—to 5.3 ms. The measurements taken by Hall show that the n-type nanoparticles have a carrier concentration of ×1017 cm−3.
