Abstract
En 中文
• This work presents the development of a temperature sensor (TES) based on a hybrid organic–inorganic nanostructure employing zinc oxide quantum wells (ZnO QWs) embedded within a core–shell poly (p-phenylene vinylene)–fullerene (PPV–C60) matrix. • The incorporation of ZnO QWs into the PPV–C60 core–shell architecture enhances charge confinement, interfacial charge transfer, and temperature-dependent carrier transport within the active layer. • The synergistic interaction between the organic semiconductor matrix and inorganic ZnO QWs results in improved thermal sensitivity, stability, and repeatability of the sensor response. • Temperature-induced variations in electrical characteristics are attributed to changes in carrier mobility, recombination dynamics, and energy-band alignment at the organic–inorganic interfaces. • The proposed TES demonstrates the potential of hybrid nanocomposite systems for low-cost, flexible, and high-performance temperature sensing applications, offering a promising platform for next-generation optoelectronic and sensing devices
