An advanced optoelectronic apparatus utilizing poly(2-amino thiophenol) adorned with a needle-shaped MnS-MnO₂ nanocomposite

A highly efficient optoelectronic device has been successfully created by integrating a nanocomposite comprised MnS-MnO₂ into a polymer matrix, specifically poly(2-amino thiophenol) (P2ATP). This resulting MnS-MnO₂/P2ATP nanocomposite boasts a unique nanoneedle-shaped structure, significantly enhancing its optical properties. Notably, this composite exhibits a bandgap of approximately 1.8 eV. The MnS-MnO₂/P2ATP thin film functions as an exceptionally efficient optoelectronic material, capable of sensing and detecting photons across a wide optical spectrum.. The device’s efficiency is assessed by determining two critical parameters: photoresponsivity (R) and detectivity (D). At a wavelength of 340 nm (nm), this optoelectronic device showcases impressive performance, delivering R and D values of 2.1 mA·W⁻¹ and 0.47 × 10⁸ Jones, respectively. Importantly, these remarkable R and D values remain consistently high across a broad optical range, extending up to 730 nm. The highest J_ph value, reaching 0.21 mA cm⁻², is achieved at 340 nm, while this value sequentially decreases to 0.14 mA cm⁻² at 730 nm. This outstanding optical performance establishes the prepared MnS-MnO₂/P2ATP nanocomposite as an exceptionally versatile and efficient optoelectronic material with the potential for various industrial applications. This promising behavior positions it as an ideal candidate for utilization in the industrial sector, where its robust and highly efficient performance can be harnessed in applications such as sensors, photodetectors, and various other optical technologies.
