Abstract: films. Our results reveal that thermal treatment plays a pivotal role in controlling grain size, crystallinity, defect density, and overall optoelectronic behaviour. Notably, a remarkable 70-fold enhancement in photoluminescence emission was observed, alongside a crystal structure morphology evolution from 3D to 0D and 2D structures through simple annealing offering transformative potential for optoelectronic applications. By elucidating the interplay between annealing conditions and film characteristics, this work provides key insights for optimizing inkjet-printed perovskite films, driving advancements in next-generation, sustainable, and high-performance printed electronics. The application of the printed films was successfully demonstrated as efficient colour conversion layers for optoelectronic devices.
