The study showed that excitons in free-standing regions emitted light more strongly, had longer lifetimes, and maintained temporal coherence over extended periods. The findings demonstrate that reducing substrate-induced energy losses and disorder can significantly improve the optical performance of these structures, and they provide an important foundation for the development of next-generation optoelectronic and quantum technologies.<\/p>\n<p>Read Asst.
