Synthesis of High Quality Inorganic Perovskite Quantum Dots via Microchannel Reactor and Their Application in LED

A microchannel reactor for rapid and efficient synthesis of high-quality inorganic perovskite quantum dot (CsPbBr₃) was proposed. By adjusting the concentration and flow rate of the precursor solution, the fluorescence spectrum can be green to blue and the corresponding wavelength is from 515 nm to 464 nm. The CsPbBr₃ NCs applied with red phosphor on a blue chip achieved a luminous efficacy of 62.93 lm/W under 20 mA current. The high efficient white LEDs demonstrated the promising potential of CsPbX₃ NCs for low-cost display, lighting, and optical communication applications.
