“…The search of high operational stability of the lasers also stimulated the development of fully inorganic perovskites with optical gain. Single mode emission at 654 nm was reported in CsPbBrI 2 films [74], spin coated on nanoimprinted polymer substrates, but no lasing was claimed by the authors, due to a particularly high linewidth of about 5 nm.…”

“…In 2012, the researchers integrated graphene into an electrically driven disk laser and realized the room‐temperature operation with a threshold current of ≈300 µA, as shown in Figure a,b. Since then, micro‐disk/cavity lasers based on layered materials such as graphene, TMDCs, and perovskites have developed rapidly. For example, the researchers achieved a 2D exciton visible‐light laser by introducing the single‐layer WS 2 into a disk cavity, as illustrated in Figure c,d.…”

In recent years, 2D layered materials, including graphene, topological insulators, transition metal dichalcogenides, black phosphorus, MXenes, graphitic carbon nitride, and metal‐organic frameworks, have attracted considerable interest due to their potential applications in the fields of physics, chemistry, biology, and energy. Their rise in the field of nonlinear photonics began around 2009 and has become an important research direction. Here, the synthesis techniques, nonlinear optical properties, integration strategies, and device applications of layered materials are reviewed. In terms of nonlinear optical properties, the focus is on saturable absorption and Kerr nonlinearity. On this basis, their applications in various pulsed lasers, including fiber lasers, solid‐state lasers, waveguide lasers, and related nonlinear optical phenomenon, are summarized. In addition, novel optical devices using layered materials, such as optical modulators, optical polarizers, optical switchers, and even all‐optical device, are also involved. It is believed that the development of 2D layered materials in the field of photonics will continue to deepen, thus laying a good foundation for its practical application.

“…By adding PEO, the diffusion of CsPbBr 3 precursors could be limited. Thus, the grain size is significantly reduced, producing high-surface-coverage, pinhole-free thin films with lower surface roughness [25,26]. The polyethylene terephthalate (PET) substrates, prior to deposition, were sonicated in deionized water, then isopropanol alcohol, for 15 min each, and then UV-ozone treated for 15 min.…”

Pressure and temperature are powerful tools applied to perovskites to achieve recrystallization. Lamination, based on recrystallization of perovskites, avoids the limitations and improves the compatibility of materials and solvents in perovskite device architectures. In this work, we demonstrate tightly compacted perovskite laminates on flexible substrates via hot-pressing and investigate the effect of hot-pressing conditions on the lamination qualities and optical properties of perovskite laminates. The optimized laminates achieved at a temperature of 90 °C and a pressure of 10 MPa could sustain a horizontal pulling pressure of 636 kPa and a vertical pulling pressure of 71 kPa. Perovskite laminates exhibit increased crystallinity and a crystallization orientation preference to the (100) direction. The optical properties of laminated perovskites are almost identical to those of pristine perovskites, and the photoluminescence quantum yield (PLQY) survives the negative impact of thermal degradation. This work demonstrates a promising approach to physically laminating perovskite films, which may accelerate the development of roll-to-roll printed perovskite devices and perovskite tandem architectures in the future.
