- Resumen
Perovskite nanocrystals have emerged as outstanding materials for optoelectronic applications due to their tunable composition, bright emission, and tolerance to defects. Among them, all-inorganic CsPbBr3 nanocrystals exhibit exceptional photoluminescence and stability, making them ideal for next-generation LEDs. However, conventional hot-injection synthesis is complex, energy-intensive, and unsuitable for scale-up. This Ph.D. thesis explores microwave-assisted synthesis as a fast, sustainable alternative, enabling precise control of crystal size and halide composition while achieving high photoluminescence quantum yields after purification. The resulting nanocrystals were successfully integrated into LEDs, showing sharp emission, high efficiency, and excellent luminance. A life cycle assessment revealed that microwave synthesis dramatically reduces energy consumption compared to conventional methods, without compromising material quality. Overall, this work demonstrates that microwave-assisted strategies combine performance and sustainability, offering a scalable route for high-quality CsPbBr3 nanocrystals and advancing their integration into practical optoelectronic technologies.
