This Collection supports and amplifies research related to SDG 7 – Affordable and Clean Energy.
This Collection highlights original research that explore synthesis and structural design of low-dimensional perovskites, optical gain mechanisms, cavity engineering, and device integration. Studies addressing challenges in stability, scalability, and operation under ambient or electrically pumped conditions are particularly welcome.
Low-dimensional perovskites have emerged as a transformative class of materials for optoelectronic and photonic applications, offering tunable band structures, strong excitonic effects, and enhanced stability compared with their three-dimensional counterparts. When integrated into laser architectures, these materials enable low-threshold, wavelength-tunable, and highly coherent light emission, marking an important frontier in nanophotonics and solid-state lighting. The significance of this field lies in its potential to unify fundamental advances in exciton physics with practical device innovations for compact, energy-efficient, and color-pure laser technologies. Recent progress has been driven by the design of two-dimensional, quasi-two-dimensional, and nanocrystal perovskites with controlled composition, dimensionality, and dielectric confinement.
