This study achieved the decoration of poly-3-methyl aniline (P3MA) with AsO-As(OH) using KSO and NaAsO on the 3-methyl aniline monomer. This resulted in a highly porous nanocomposite polymer composite with wide absorption optical behavior, an average crystalline size of 22 nm, and a 1.73 eV bandgap. The photoelectrode exhibited a great electrical response for electroanalytical applications, such as photon sensing and photodiodes, with a J of 0.015 mA/cm and J of 0.004 mA/cm. The variable J values ranged from 0.015 to 0.010 mA/cm under various monochromatic filters from 340 to 730 nm, which demonstrates high sensitivity to wavelengths. Effective photon numbers were calculated to be 8.0 × 10 and 5.6 × 10 photons/s for these wavelength values, and the photoresponsivity (R) values were 0.16 and 0.10 mA/W, respectively. These high sensitivities make the nanocomposite material a promising candidate for use in photodetectors and photodiodes, with potential for commercial applications in highly technological systems and devices. Additionally, the material opens up possibilities for the development of photodiodes using n- and p-type materials.
本研究通过在3-甲基苯胺单体上使用KSO和NaAsO实现了聚-3-甲基苯胺（P3MA）与AsO-As(OH)的修饰。这产生了一种具有高度多孔性的纳米复合聚合物复合材料，具有宽吸收光学行为，平均晶体尺寸为22纳米，带隙为1.73电子伏特。该光电极在诸如光子传感和光电二极管等电分析应用中表现出良好的电响应，其J值为0.015 mA/cm²，J值为0.004 mA/cm²。在340至730纳米的各种单色滤光片下，可变的J值范围为0.015至0.010 mA/cm²，这表明对波长具有高灵敏度。对于这些波长值，计算出的有效光子数分别为8.0×10¹⁴和5.6×10¹⁴个光子/秒，光响应度（R）值分别为0.16和0.10 mA/W。这些高灵敏度使得该纳米复合材料成为用于光电探测器和光电二极管的有前途的候选材料，在高科技系统和设备中具有商业应用潜力。此外，该材料为使用n型和p型材料开发光电二极管开辟了可能性。
