Abstract: Blue perovskite electroluminescent devices offer outstanding color purity and cost-effective fabrication, making them highly promising for applications in full-color displays and white light illumination. Quasi-two-dimensional (quasi-2D) perovskites, owing to their outstanding optical properties and structural tunability, have showed broad application prospects. However, the regulation of their crystallization kinetics is critical for optimizing film quality and luminescent performance. This review summarizes the optical and photophysical characteristics of blue quasi-2D perovskites, with a particular focus on strategies for controlling their crystallization behavior through component management, additive engineering, post-treatment technology, and interfacial modification. Studies demonstrate that precise control crystallization kinetics of quasi-2D perovskites can significantly enhance uniformity and photoluminescence quantum yield of the films, while also improving the external quantum efficiency and operational stability of the devices. Finally, the paper analyzes the current challenges and limitations in this field, and provides a perspective on future development directions toward high-efficiency, high-brightness, and long-lifetime blue perovskite electroluminescent devices, offering theoretical insights and technical guidance for future research.

Key words: quasi-2D perovskite; blue electroluminescent device; component management; additive engineering; post-treatment technology; interfacial modification; optoelectronic property
