“…Lead halide perovskite quantum dots (QDs) have attracted extensive attention, with outstanding prospects for usage in light-emitting diodes (LEDs), photoelectric sensors, solar cells, and lasers [ 1 , 2 , 3 , 4 , 5 , 6 ]. As an all inorganic lead halide perovskite quantum dot, CsPbX 3 (X = Cl, Br, I) has become a promising fluorescence material because of its low cost, narrow emission full width at half maximum (FWHM) (12–42 nm), high luminescence efficiency (90%), stable photochemical property, and simplicity of modification.…”

The ability to precisely obtain tunable spectrum of lead halide perovskite quantum dots (QDs) is very important for applications, such as in lighting and display. Herein, we report a microchannel reactor method for synthesis of CsPbBr3 QDs with tunable spectrum. By adjusting the temperature and velocity of the microchannel reactor, the emission peaks of CsPbBr3 QDs ranging from 520 nm to 430 nm were obtained, which is wider than that of QDs obtained in a traditional flask without changing halide component. The mechanism of photoluminescence (PL) spectral shift of CsPbBr3 QDs was investigated, the result shows that the supersaturation control enabled by the superior mass and heat transfer performance in the microchannel is the key to achieve the wide range of PL spectrum, with only a change in the setting of the temperature controller required. The wide spectrum of CsPbBr3 QDs can be applied to light-emitting diodes (LEDs), photoelectric sensors, lasers, etc.

“…In this technique, insulating polymeric materials were used as matrix to encapsulate nanostructures or accompany conjugated polymers. Over the past 5 years, the polymer fiber matrixes have been successfully electrospun into HP based luminescent fibers, such as polyvinylpyrolidone (PVP), [ 101–104 ] polyacrylonitrile (PAN), [ 105,106 ] poly(methlymethacrylate) (PMMA), [ 107–109 ] polystyrene (PS), [ 110–114 ] polyvinyl alcohol (PVA), [ 112,115 ] polyvinyl acetate (PVAc), [ 114 ] polyurethane (PU), [ 116,117 ] styrene‐butadiene‐styrene (SBS), [ 118,119 ] and poly(vinylidene fluoride) (PVDF). [ 120,121 ] Since electrospinning requires chain entanglement and perovskite materials are not being able to electrospun without any matrix agent, polymer selection is crucially important concerning to solubility and spinnability.…”

“…proposed a multistep approach to form perovskite nanoparticles within the uniaxial polymer fibers. [ 101 ] To form OIHP nanoparticles, a DMF solution of lead iodide (PbI 2 )/PVP mixture was electrospun and the collected fiber membranes were immersed into an isopropyl alcohol solution of methyl ammonium iodide (MAI). Unlike first example, iodine based OIHP nanocrystals were formed through PAN composite fibers by calcination of composite fiber at an elevated temperature (150 °C) for formation of mesoporous surface structure after electrospinning of PbI 2 /PAN.…”

Perovskite nanomaterials have been revealed as highly luminescent structures regarding their dimensional confinement. In particular, their promising potential lies behind remarkable luminescent properties, including color tunability, high photoluminescence quantum yield, and the narrow emission band of halide perovskite (HP) nanostructures for optoelectronic and photonic applications such as lightning and displaying operations. However, HP nanomaterials possess such drawbacks, including oxygen, moisture, temperature, or UV lights, which limit their practical applications. Recently, HP‐containing polymer composite fibers have gained much attention owing to the spatial distribution and alignment of HPs with high mechanical strength and ambient stability in addition to their remarkable optical properties comparable to that of nanocrystals. In this review, the fabrication methods for preparing nano–microdimensional HP composite fiber structures are described. Various advantages of the luminescent composite nanofibers are also described, followed by their applications for photonic and optoelectronic devices including sensors, polarizers, waveguides, lasers, light‐down converters, light‐emitting diode operations, etc. Finally, future directions and remaining challenges of HP‐based nanofibers are presented.

“…Recently, methylammonium Pb halide perovskites demonstrated impressive progress due to their excellent absorption properties. In this study, one-dimensional PbI 2 /PVP composite fibers were prepared via an electrospinning process (Table 5 ) [ 143 , 144 ]. The XRD analysis of PbI 2 /PVP composite fibers shows multiple crystalline phases, which indicates that PbI 2 powder forms a composite fiber with PVP after dissolution and electrospinning without a high-temperature and high-voltage process.…”

The progress made by the scientific community in emerging photovoltaic technologies over the past two decades has been outstanding. Numerous methods have been developed for the preparation of hybrid organic–inorganic perovskite solar cells. The power conversion efficiency has been up to 14% by a one-step vacuum deposition technique. A serious concern is the toxicity of the materials. In this review, several methods aimed at resolving these problems to some extent have been compiled, including eco-friendly synthesis. Further efficiency enhancements are expected following optimization, and a better fundamental understanding of the internal electron charge transfer, electron–hole diffusion to the corresponding layers, flexibility, and stability-dependent bandgaps is reported. This paper explores the green synthesis of organic–inorganic perovskites for industrialization. Concerning the above facts, a simple low-cost model called “dispersed photovoltaic cells” is presented.
