Advanced Laser Nanofabrication Technologies for Perovskite Photonics

Abstract

Halide perovskites have become a versatile platform not only for optoelectronic devices but also for modern optics and nanophotonics. Perovskite nano‐ and micro‐particles, metasurfaces, and photonic crystals demonstrate their applicability for directional enhanced photo‐ and electro‐luminescence, lasing, as well as for improving the performance of optoelectronic devices. However, ionic nature makes perovskites water soluble, while their high sensitivity to diverse chemicals complicates their patterning toward the formation of functional, high‐quality nanostructures. Here, recent progress on emerging laser technologies for processing and nanopatterning of halide perovskites, as well as their applications in designing advanced light‐emitting systems and controlling light at the nanoscale is overviewed. Special emphasis is made on the processes underlying the interaction of laser radiation with perovskites to disclose new avenues for their surface and volume modification with ultra‐high precision and a high degree of material's property control.

Femtosecond laser ultrafast photothermal exsolution

“…Employing higher power lasers accompanied by further increasing scan speed to m•s −1 can make this technique more efficient and practical for industrial applications, rather than being limited in the lab-scale. From material perspective, black and darkblue ZrO 2 can also be potentially applied as solar absorbers [24,52], pigments and dyes [53], and in decoration, implant dentistry [54], photocatalyst [55] fields; while from technique perspective, the applications of our method is as well compatible with those of fs laser ablation/structuring, patterning, and material synthesis within the scope of optics/photonics [56][57][58][59][60][61], energy [62], photoelectronic [63], flexible electronics [64], wettability [65,66], biomimetic [67], bubble/gas manipulation [68], stimulus-responsive interfaces [69], miniaturized robotics [70], fundamental studies [71][72][73][74], etc.…”

Reversible Thermochromic Perovskite-Based Dynamic Optical Encryption and Holographic Inference

“…In the past decade, perovskites have emerged as a species of prospective materials to construct high-performance optoelectronic devices such as solar cells, photodetectors, and light-emitting diodes due to their long carrier lifetime, high carrier mobility, and solution processability. − Based on their superior properties of a high refractive index (approximately within the interval of 2.2–2.55) and a flexible optical band gap, perovskites have recently started to cut a striking figure in information photonic devices, for instance, microlasers, , nonlinear emission, optical data storage, metasurfaces, etc. Due to the abundant categories of chemical constituents and lattice structures, perovskite species can provide a diversified and selectable material platform to achieve dynamic photonic devices.…”
