Metal-halide perovskites (MHP) have gained prominence as highly promising and cost-effective optoelectronic materials, owing to their exceptional optoelectronic properties and versatile fabrication methods [1-6]. These materials find applications across diverse fields, including solar cells, light-emitting diodes, photodetectors, and quantum emitters. Quantum confinement, can bring to light unexpected and advantageous characteristics, fostering the development of high-performance devices.

An effective approach to induce quantum confinement involves creating layers of quantum-confined materials through the deposition of multiple thin films. Thermal evaporation stands out as a particularly promising technique for fabricating halide perovskite films. It provides precise control over layer thickness, enables fine-tuning of composition, ensures stress-free film deposition, and allows modification of surface properties. The utilization of thermal evaporation in perovskite fabrication has broadened the possibilities of thin film production, showcasing its capability to generate ultrathin perovskite films serving as the foundation for multi-quantum well structures.

This method facilitates the manipulation of growth properties, influencing the optoelectronic characteristics of nanoscale thin films, and inducing quantum confinement effects within the structure. The precise control over photoluminescence through quantum confinement opens up a wide array of possibilities for unconventional optoelectronic properties and novel applications of perovskites [7-10].
