dc.description.abstract | This study presents an investigation into the fabrication, characterization, and performance analysis of cavity-free and stretchable white lasers based on 2D glutamine(GLN)-functionalized WS2 quantum dots (QDs) enhanced by the integration of Au nanoparticles (NPs) and wrinkled graphene structure. Incorporating Au NPs introduces localized surface plasmon resonance (LSPR), which enables to enhance of the light-matter interaction, resulting in reduced lasing thresholds. The stretchable nature of these devices is demonstrated through mechanical bending tests, showcasing their potential for seamless integration into flexible and wearable applications. Furthermore, the absence of a cavity in the laser structure simplifies the device design and fabrication process, making them highly versatile and scalable. The GLN-functionalized WS2 QDs exhibit strong photoluminescence emission, and their integration with wrinkled graphene structure and Au NPs creates a synergistic effect that enhances the emission efficiency and enables the realization of cavity-free lasing. The extensive characterization and analysis of the emission spectra under different deformation ratios provide valuable insights into the tunability and reliability of these devices as well as the importance of light trapping due to wrinkled graphene structure. The findings of this study underscore the significant potential of localized surface plasmon resonance and wrinkled graphene structure induced stretchable and cavity-free white lasers based on 2D GLN-functionalized WS2 quantum dots for a wide range of applications in the field of flexible and wearable photonics, which is a critical step toward the development of next-generation optoelectronic devices with enhanced performance and versatility. | en |
