5. Spin-Engineered Exciton Dynamics for Next-Generation Perovskite Lasers
Our research explores lasing phenomena in emerging semiconductor nanomaterials, with a particular emphasis on how excitonic spin dynamics can be harnessed to design novel optical gain mechanisms. Lead halide perovskite nanocrystals serve as an ideal model system due to their outstanding optical gain, defect tolerance, and solution processability, making them strong candidates for low-threshold and tunable lasers. However, conventional lasing strategies have largely relied on singlet excitons, thereby overlooking spin-allowed triplet channels that could substantially enhance quantum efficiency. Building on our recent discovery of coexisting bright singlet and triplet excitons in CsPbBr₃ nanocrystals, we aim to generalize these principles toward developing lasing platforms that exploit both radiative channels across diverse material systems. Our approach integrates microcavity architectures, exciton–polariton coupling, and Rashba engineering to stabilize and amplify bright triplet states under optical pumping. By employing polarization-resolved and time-resolved spectroscopies, we investigate the interplay between singlet–triplet intersystem crossing, exciton diffusion, and stimulated emission processes. Looking forward, we will expand beyond perovskites to explore other novel nanomaterials — such as chalcogenide semiconductors, metal–organic frameworks, and low-dimensional quantum materials — to establish a universal framework for spin-engineered lasing. Ultimately, our goal is to realize a new generation of lasers with high efficiency, spectral tunability, and operational stability, paving the way for on-chip coherent light sources and quantum photonic technologies.
