“…These nanoparticles demonstrated ASE in a broad range of wavelengths (524.5-620 nm) with pump thresholds between 22 and 55 μJ/cm 2 under femtosecond excitation. CsPbBr 3 QDs also present an efficient generation of PL under TPA, as it has been studied in [108]. Indeed, a film of nanoparticles revealed the generation of ASE under TPA with pump fluencies above 0.8 mJ/cm 2 , smaller thredhold than that obtained with semiconductor nanocrystals.…”

“…Therefore, HPVKs layers have been successfully applied in a wide range of photonic devices, such as photodetectors [91,92] or light emitting diodes [90,93]. In addition, since HPVKs present a fast carrier formation and long recombination time, they are promising materials to reduce the stimulated emission threshold in active devices [94][95][96][97][98][99][100][101][102][103][104][105][106][107][108][109], as it has been nicely reviewed in [90].…”

Abstract. Semiconductor nanocrystals have arisen as outstanding materials to develop a new generation of optoelectronic devices. Their fabrication under simple and low cost colloidal chemistry methods results in cheap nanostructures able to provide a wide range of optical functionalities. Their attractive optical properties include a high absorption cross section below the band gap, a high quantum yield emission at room temperature, or the capability of tuning the band-gap with the size or the base material. In addition, their solution process nature enables an easy integration on several substrates and photonic structures. As a consequence, these nanoparticles have been extensively proposed to develop several photonic applications, such as detection of light, optical gain, generation of light or sensing. This manuscript reviews the great effort undertaken by the scientific community to construct active photonic devices based on these nanoparticles. The conditions to demonstrate stimulated emission are carefully studied by comparing the dependence of the optical properties of the nanocrystals with their size, shape and composition. In addition, this paper describes the design of different photonic architectures (waveguides and cavities) to enhance the generation of photoluminescence, and hence to reduce the threshold of optical gain. Finally, semiconductor nanocrystals are compared to organometallic halide perovskites, as this novel material has emerged as an alternative to colloidal nanoparticles.

“…37 Suspensions of such NCs showed ASE and lasing when infiltrated into a capillary tube. 110 Wang et al 36 demonstrated low-threshold one-, two-and multi-photon pumped ASE from 9 nm CsPbBr 3 NCs with large two-photon absorption cross-sections. These studies indicate that both hybrid and inorganic perovskite NCs are promising for lowthreshold laser devices.…”

Colloidal lead halide perovskite nanocrystals: synthesis, optical properties and applications

Lead halide perovskite nanocrystals (NCs) are receiving a lot of attention nowadays, due to their exceptionally high photoluminescence quantum yields reaching almost 100% and tunability of their optical band gap over the entire visible spectral range by modifying composition or dimensionality/size. We review recent developments in the direct synthesis and ion exchange-based reactions, leading to hybrid organic-inorganic (CH 3 NH 3 PbX 3 ) and all-inorganic (CsPbX 3 ) lead halide (X = Cl, Br, I) perovskite NCs, and consider their optical properties related to quantum confinement effects, single emission spectroscopy and lasing. We summarize recent developments on perovskite NCs employed as an active material in several applications such as light-emitting devices, solar cells and photodetectors, and provide a critical outlook into the existing and future challenges.

Organic–inorganic lead halide perovskites are promising optoelectronic materials resulting from their significant light absorption properties and unique long carrier dynamics, such as a long carrier lifetime, carrier diffusion length, and high carrier mobility. These advantageous properties have allowed for the utilization of lead halide perovskite materials in solar cells, LEDs, photodetectors, lasers, etc. To further explore their potential, intrinsic properties should be thoroughly investigated. Single crystals with few defects are the best candidates to disclose a variety of interesting and important properties of these materials, ultimately, showing the increased importance of single‐crystalline perovskite research. In this review, recent progress on the crystallization, investigation, and primary device applications of single‐crystalline perovskites are summarized and analyzed. Further improvements in device design and preparation are also discussed.
