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.
期刊介绍:
Instruments and Experimental Techniques is an international peer reviewed journal that publishes reviews describing advanced methods for physical measurements and techniques and original articles that present techniques for physical measurements, principles of operation, design, methods of application, and analysis of the operation of physical instruments used in all fields of experimental physics and when conducting measurements using physical methods and instruments in astronomy, natural sciences, chemistry, biology, medicine, and ecology.
