摘要
Perovskite nanoparticles (PeNPs) have been extensively studied for optoelectronic applications, owing to their extremely high photoluminescence quantum yield, tunable band gap, and exceptionally narrow emission spectra. Therefore, PeNPs are considered excellent candidates for the development of high-efficiency, low-cost, wide-gamut, and high-purity color displays. However, their synthesis typically involves multistep cumbersome processes that might hinder commercial development. Herein, green light-emitting diodes (LEDs) prepared by using all-inorganic PeNPs CsPbBr3 synthesized at room temperature (RT) are reported and their performance compared with those prepared by a traditional hot-injection method. Insights into the morphology and optoelectronic properties of RT PeNPs are provided through AFM and TEM and employing them in LEDs.
