Large-Scale Production of Ligand-Engineered Robust Lead Halide Perovskite Nanocrystals by a Droplet-Based Microreactor System

Yuhao Geng et al.

Summary: Cesium lead halide perovskite nanocrystals (CLHP NCs) have a wide range of potential applications, but their ionic nature and sensitivity to moisture, oxygen, and heat make it challenging to maintain their crystal structure and optical properties. This study proposes solutions for two key issues in the development of CLHP NCs and successfully fabricates nanocrystals with high stability and optical performance.

Kinetic analysis of the growth behavior of perovskite CsPbBr3 nanocrystals in a microfluidic system

Xiaobing Tang et al.

Summary: In this study, the growth behavior of CsPbBr3 nanocrystals synthesized in a microfluidic system was analyzed by establishing the relation between bandgap and flow rate. The results showed that the size of the nanocrystals is inversely proportional to the flow rate, and increasing synthesis temperature leads to a wider size distribution.

Ultrasound-assisted gas-liquid mass transfer process in microreactors: The influence of surfactant, channel size and ultrasound frequency

Qiang Zhang et al.

Summary: The study focuses on the impact of ultrasound on gas-liquid Taylor flow in ultrasonic microreactors, showing that bubble oscillation and mass transfer behavior are influenced by both frequency and channel dimensions. Bubble oscillation amplitude decreases with smaller channel dimensions, and more significant mass transfer enhancement is observed at lower frequencies. The addition of surfactant can further increase the mass transfer effect.

Nucleation-controlled growth of ultra-small perovskite quantum dots for bright blue light-emitting diodes

Shuhua Tu et al.

Summary: An effective synthesis strategy for ultra-small blue CsPbBr3 quantum dots (QDs) was reported, using PbBr2 clusters as nucleation sites and reacting with Cs-oleate at relatively low temperatures. The emission wavelength of CsPbBr3 QDs can be easily tuned by the amount of Cs-oleate or reaction temperature, with a maximum photoluminescence quantum yield reaching above 64%. The CsPbBr3 QDs were further coated with superhydrophobic fluorinated silica and successfully applied in blue light-emitting diodes (LEDs), providing a new synthesis strategy for efficient and stable blue PQDs.

Research on the influence of polar solvents on CsPbBr3 perovskite QDs

Yifang Sun et al.

Summary: This study investigated the effects of different polar solvents on all-inorganic perovskite quantum dots (QDs) and found that polar solvents have various effects on QDs, with the main impact being on the ligands. The polarity of the solvent was found to correlate with the degree of impact on the stability of the all-inorganic perovskite QDs.

Synthesis of CsPbBr3 perovskite nanocrystals with acoustically actuated millisecond mixing

Chun Kiu Ng et al.

Summary: The rapid nucleation and growth dynamics of metal halide perovskite nanocrystals (PNCs) pose challenges in controlling their ensemble evolution and scaling, but continuous flow with efficient acoustic mixing can achieve near complete mixing in <23 ms. This allows for superior control of nanocrystal formation stages and the evolution into structurally controlled PNCs with minimal polydispersity.
