“…They subsequently used the FAPbBr 3 and Cs 0.17 FA 0.83 PbBr 3 as gain layers together with the optimized DBR structures, and good lasing performance was demonstrated with the following characteristics: high quality factors of 1420 and 1350; low thresholds of 18.3 and 13.5 μJ/cm 2 , respectively; and the corresponding stable lifetimes of 20 h and >35 h [85,86]. Room temperature CW pumped VCSEL-based MAPbBr 3 and MAPbI 3 were reported at pump thresholds of 89 and 13 W/cm 2 , respectively [87,88]. This finding is a huge step towards achieving more efficient CWs and electric pumped perovskite lasers.…”

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.

“…Another kind of periodic structure, distributed Bragg reflectors (DBRs) with high reflectivity have also been used to implement VCSELs. Recently, Alias et al reported a green perovskite VCSELs by CW operation at room temperature . They synthesized MAPbBr 3 thin films between PMMA layers as active region in a vertical cavity deposited by dielectric DBR, as shown in Figure d.…”

Continuous‐wave (CW) operated lasers are regarded as a stepping stone to the development of electrically driven lasers and crucial for practical application in high‐density integrated optoelectronic devices. Recently, metallic halide perovskites are demonstrated as excellent gain materials for CW lasers owing to their large optical absorption coefficient, low defect density, long diffusion length, and suppressed Auger recombination rate. Here, the latest research advances on CW pumped perovskite lasers are reviewed. First, the recent research advances on CW lasing in perovskite thin film are highlighted. Then, CW lasing in CsPbBr3 perovskite nanowires is briefly introduced. The comparison of lasing thresholds in CW perovskite lasers is made and discussed. Finally, the importance of such perovskite CW lasers is emphasized, while a perspective on the potential opportunities and remaining challenges of perovskite‐based CW lasers is proposed.

Developing effective strategy to passivate surface defects in quantum dots (QDs) is critical to achieving high‐efficiency and long‐life perovskite light‐emitting diodes (LEDs). Here, the supramolecular interaction underpinning of organic‐inorganic components is exploited and a facile method is proposed to generate multiple‐hydrogen‐bonded supramolecular‐perovskite crystal structures on QD surfaces by introducing O‐Tolylbiguanide (O‐Tg) during QD synthesis, enabling bright, conductive, and water‐resistant CsPbI3 QDs. Compared with commonly used oleic acid and oleylamine ligands, the biguanide functional group in O‐Tg not only forms multiple hydrogen bond interactions with lead halide octahedra passivating both bridging‐ and terminal‐halogen ion defects, but also compatibly occupies the A‐site position stabilizing the crystal structure simultaneously. With fewer nonradiative defects and introduced hydrophobic benzene rings preventing eroding of polar molecules, CsPbI3 QDs exhibit remarkable photoluminescence quantum yields of 96%, and their film can be submerged in water for 30 h without degrading. The corresponding LEDs display a high external quantum efficiency (21.2%) and offer superior operational stability with a lifetime (T90) of 25 h at a constant current density as high as 50 mA cm−2.
