Photoinduced phase segregation in mixed halide perovskites has received considerable attention due to its critical roles in diminishing device performance in photovoltaic and light‐emitting applications. Here, dynamic photoinduced phase segregation and dark recovery in mixed halide perovskite single crystal microplatelets are investigated, combining depth‐resolved, temporal‐resolved, and detection‐wavelength selective spectroscopic imaging techniques. Under identical illumination, the edges and interior of microplatelets exhibit significantly different phase segregation. An intimate correlation of PL dynamics between I‐phase and Br‐phase indicates that the halide substitution is the dominant effect. In the dark, the phase‐segregated crystals reversibly recover to the stable equivalence. This work clarifies the critical role of the edge state of the microplatelets and reveals the physical mechanism of phase segregation in mixed halide perovskites, which is of crucial importance for their applications in photovoltaics and photonics.

“…Zhou et al realized the effective F-P cavities in CsPbX 3 micro/nanorods with lengths ranging from ~2-20 μm with low thresholds of (~14.1 μJ/cm 2 ), high quality factor (~3500) and tunable lasing wavelength (428-668 nm) under 360 nm laser with 100 fs and 1 kHz ( Figure 4A) [63]. Subsequently, Wang et al reported the multiphoton-pumped lasing from CsPbX 3 nanorods with thresholds of ~0.6 and 1.7 mJ/cm 2 under excitations of 800 and 1200 nm with 80 fs and 1 kHz [65]. Meanwhile, Hu et al demonstrated F-P lasing in CsPbBr 3 microcubes with high quality factor of 1150 under optical excitation (800 nm, 35 fs, 1 kHz), as described in Figure 4B [64].…”

AbstractThe rapid advancement of perovskite-based optoelectronics devices has caught the world’s attention due to their outstanding properties, such as long carrier lifetime, low defect trap density, large absorption coefficient, narrow linewidth and high optical gain. Herein, the photonic lasing properties of perovskites are reviewed since the first stimulated emission of perovskites observed in 2014. The review is mainly focused on 3D structures based on their inherently active microcavities and externally passive microcavities of the perovskites. First, the fundamental properties in terms of crystal structure and optical characteristics of perovskites are reviewed. Then the perovskite lasers are classified into two sections based on the morphology features: the ability/inability to support lasing behaviors by themselves. Every section is further divided into two kinds of cavities according to the light reflection paths (Standing wave for the Fabry–Pérot cavity and travelling wave for the Whispering-Gallery-Mode cavity). The lasing performance involves fabrication methods, cavity sizes, thresholds, quality factors, pumping sources, etc. Finally, some challenges and prospects for perovskite lasers are given.

“…A distinct blue‐shifts of the lasing modes as the increase of the excitation fluence fits well with the band filling effect of Burstein–Moss theory. An electron–hole plasma is responsible for the multiphoton pumped lasing . Hu et al reported the two‐photon pumped FP cavity lasing with stability and wavelength tunability from the facile solution‐processed CsPbX 3 perovskite microcubes.…”

Halide perovskites have shown great potential in optoelectronic applications, such as a record photovoltaic efficiency of 23.3%, and an achievement of external quantum efficiency beyond 20% in perovskite light‐emitting diodes, as well as other promising demonstrations of light‐emitting transistors and photodetectors. Moreover, the extraordinary optoelectronic properties of optical absorption, high photoluminescence quantum yield, low non‐radiative recombination rates, large and balanced charge‐carrier mobilities, and high gain coefficients extend their applications into the coherent light sources (laser) field. However, although halide perovskites have made great progress, the realization of solid‐state electrically pumped lasers has not been achieved yet. This review starts with a discussion of the structure, optical properties, and gain behaviors of various perovskite materials. Then, the rapid advances of perovskite‐based laser applications are reviewed, in which they are mainly classified into three sections: optically pumping lasers, strong‐coupling lasers, and continuous‐wave pumped lasers. Finally, the conclusions and some remaining challenges for perovskite electrically driven lasers are highlighted.
