“…Moreover, the cost of production is relatively high compared to the cost of production via the solution phase. A simple approach to synthesizing rectangular-shaped microdisks was first demonstrated by Wang et al [96] In this work, the synthesis of perovskite microdisks was initiated by the drop-coating of CH 3 NH 3 Br•PbBr 2 (0.1 m) onto a hydrophobic substrate. They also mentioned that the drop-casted solution and dichloromethane (DCM) require careful observation to achieve high-performance waveguide.…”

ruthenium molecular dye, wide absorption range, direct and tunable bandgaps, superior charge carrier mobility, and long carrier diffusion length. [6,[43][44][45] Although it has been synthesized for over 100 years, Mitzi et al. were the first to investigate the electrical properties of tin-based perovskite in 1994, [46] which was later used in numerous devices, including field effect transistors (FETs) and LEDs. [47][48][49] The attention toward metal halide perovskites sparked yet again in 2009, [42] and they were later named one of the most promising emerging technologies in 2016. In brief, metal halide perovskites can be divided into two types based on their crystal structure motif: (i) 3D-structured perovskite (AMX 3 ) and (ii) 2D-structured perovskite (A 2 MX 4 ). The structure of the perovskite could either be 2D or 3D, while the dimensions of the perovskite probably belong to 0D-3D. The term "perovskite" implies to the general class of materials derived from an elemental composition of AMX 3 and demonstrates the crystal structure of perovskite crystal CaTiO 3 , where the divalent metal M resides at the body center and surrounded by six X-anions located at the face centers in an octahedral cluster. The MX 6 in the octahedral cluster may form an extended 3D structure by all-corner-connected type with A-cation sitting at the center. It could also form a 2D perovskite when the 3D perovskite network is cut into one-layer-thick slices along the 〈100〉 direction and separates them apart. In principle, 2D perovskite is the easiest to synthesize because of its natural layered structure, which is held together by weak van der Waals forces. Dou et al. reported the large-scale synthesis of the monolayer (C 4 H 9 NH 3 ) 2 -PbBr 4 by a chemical method. [50] Along the same lines, several groups have prepared and characterized nanomaterials composed of various forms of perovskites. [51][52][53] Also, our group has recently successfully prepared a low-dimensional mixed 2D/3D perovskite using the protonated salt of amino valeric acid iodide (AVAI) as an organic precursor mixed with PbI 2 , in which a yellowish film was containing needle-like crystallite formed. [54] In this topical review, we present the latest advances in the synthesis of low-dimensional perovskites and the growth mechanism to develop a strategy to achieve best performing devices. Later, we focus the instability and a cost-effective solution to circumvent this problem, which is vital for the eventual deployment of perovskite solar cells to consumers market. We present an analysis of the origins for instability in perovskite solar cells, and present a summary of the main achievements and possible future developments of these low-dimensional perovskite. [2,55] Perovskite solar cells have been heralded as one of the most promising emerging technologies in 2016 because of the very high power conversion efficiency of 22% and the low cost of generating electricity compared to even fossil fuels. These are formed with various dimensionalities and can be fully mani...

“…[14,21] Meanwhile, unique properties have also been engineered into the MAPbX 3 microlasers, e.g., ultralow threshold, high quality (Q) factors, unidirectional output, and vertical cavity surface emission. [22,23] With the developments of nanofabrication technologies, distributed feedback Bragg (DFB) laser and circular microdisk lasers with precise wavelength control and wellpreserved optical gain have been experimentally realized by either inductively coupled plasma etching or nanoimprinting. [24][25][26] Associated with the developments of isolated devices, lead halide perovskites devices arrays have attracted considerable research attention due to their potential applications in coherent light arrays, charge-coupled device (CCD) arrays, and integrated optoelectronic circuits.…”

Lead halide perovskites have recently attracted attention due to their outstanding photoelectric properties. Hence, perovskite-based optoelectronic devices are widely studied. Herein, a simple solution-based one-step anti-solvent method to produce well-controlled and uniform CH 3 NH 3 PbBr 3 -based micro-devices is reported. It is confirmed that the size and mode numbers of the self-assembled microdisk cavities can be well controlled by modifying the size of the SiO 2 microdisks on the substrate or changing the concentration of the perovskite precursor. With this simple and robust method, the produced CH 3 NH 3 PbBr 3 microdisk arrays are extremely uniform in both their size distribution and emission spectra. Moreover, a perovskite photodetector array with fast rise (<8.3 ms) and decay (<8.3 ms) times was fabricated by periodically patterning the substrate. Based on the high controllability and high reproducibility of the patterned CH 3 NH 3 PbBr 3 microdisk arrays, this cost-effective and mass-manufacturable approach significantly increases the production yield of lead halide perovskite microdevices and boosts their ability to be used in practical applications.

“…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].…”

“…As a result, the nanostructures demonstrated a narrow lasing line of FWHM = 0.5 nm at 557 nm when they were optically pumped above 3.6 μJ/cm 2 . Recently unidirectional laser emission from CH 3 NH 3 PbBr 3 Perovskite microdisks was demonstrated [102]. For this purpose fabrication was carefully controlled in order to synthetized a microdisk connected to a nanowire, both with rectangular shape.…”

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.
