Avances recientes en el procesamiento de perovskitas mediante láser de femtosegundos para aplicaciones ópticas

In recent years, with the rapid development of new energy and optoelectronic technologies, perovskite materials have become a research hotspot of common interest in both academic and industrial communities due to their excellent optoelectronic properties, low-cost fabrication processes, and diverse application scenarios. However, achieving efficient and high-precision processing of perovskite materials remains a key challenge hindering their broader application. In this context, femtosecond laser processing technology, leveraging its ultra-short pulse duration and high-precision machining capabilities, has opened up new possibilities for research into and application of perovskite materials. This review summarizes the mechanisms and recent advances in femtosecond laser micro/nano-processing of perovskite single crystals, glasses, and polymer thin films, systematically outlines relevant methods and their unique advantages, provides an in-depth discussion on the application potential of femtosecond laser direct writing in the field of perovskite luminescence, and offers prospects for future optimization and improvement of femtosecond laser-based preparation and processing techniques. The findings presented are expected to provide important theoretical support and technical reference for further research and practical applications of perovskite materials.
