Recent Advances and Challenges of Nanorods in Optoelectronics: A Comprehensive Review

Optical, electrical, and geometric specifications of one-dimensional (1D) nanostructures, including nanorods, have transformed optoelectronic procedures. This paper discusses the application of nanorods in enhancing solar cells, LCDs, photodetectors, and displays. This shows that the ways to alter optical and electrical properties for various applications are possible. The review highlights advances that have taken place with these nanostructures in luminescent optoelectronics, such as enhancement in photoluminescence, improvement in charge carrier mobility, and localized surface plasmon resonance. The demonstration of their extensive use in energy harvesting, sensing, and high-resolution displays is mentioned as a major finding. Nevertheless, such obstacles as scalability, stability, and environmental impact still exist, and large-scale implementation is a challenge. To address these challenges, new strategies in the field of surface modification and integration of materials have been reported. Based on a comprehensive literature review, several experimental studies, synthesis innovations, and device integrations were reported. The review, by using correlation between nanorod structural and functional characteristics and device performances, presents paths to the optimization of optoelectronic efficiencies and durabilities. The findings underscore the possible game-changing potential of nanorods in optoelectronics, culminating in a new breed of energy-threatening, miniaturized, and flexible devices. Accordingly, the review provides the framework for future studies, where interdisciplinary studies are necessary to harness the potential of nanorods as next-generation optoelectronics.
