Abstract

Perovskite quantum dots (PQDs), as the promising materials for the blue light-emitting diodes (LEDs), own huge advantages as ultra-high color purity, flexibility and whole-spectrum tunability. Through dimensional and compositional engineering, PQD-LEDs have shown superiority in deep-blue light emission. However, compared with the fast development of red and green PeLEDs, the electroluminescent performance of PQD-LEDs has faced more obstacles. In this review, we aim to explore and state the uniqueness and the possible solutions for the bottleneck problems of the PQD-LEDs.
Keywords: perovskite quantum dots; blue-light emission; light-emitting diodes; dimensional engineering; compositional engineering perovskite quantum dots; blue-light emission; light-emitting diodes; dimensional engineering; compositional engineering
