Advances in Near-Infrared Organic Micro/Nanolasers

摘要

Near-infrared (NIR) micro/nanolasers hold great potential for integration ofoptoelectronic circuitry, medical diagnosis, sensing, and so forth. For the lasermedium, organic gain molecules are highly attractive in NIR micro/nanolasersdue to the inherent merits of abundant excited-state processes, chemicaltunability, and solution processing. Herein, the recent advances of NIRorganic micro/nanolasers on nondoped molecule aggregates are reviewedfrom the aspects of gain materials, fabrication of self-assembled microcavities,and NIR lasing actions, as well as some typical examples in applications,supporting the effective construction of internal quantitative relationshipof gain molecular structures, excited-state gain processes, self-assembledmicro/nanostructures, and NIR lasing performance. Finally, conclusion andoutlook are given, aiming at offering valuable revelation for further developmentof high-performance NIR organic micro/nanolasers.
