Controllable synthesis of Cu-based quantum dots/nanocrystals and application in white light-emitting diodes

Abstract

Lead-free copper-based quantum dots (QDs)/nanocrystals (NCs) with facile preparation method and low price are promising to replace traditional expensive phosphors for white light-emitting diodes (W-LEDs) applications. In this article, the...
