Abstract
We report simultaneous photoluminescence and electroluminescence single-particle study of nanocrystals of inorganic halide perovskite CsPbBr3, as well as of ternary I-III-IV semiconductor quantum dots.
Highlights
Due to their exceptional excitonic properties such as strong absorption and efficient narrow-band emission, lead halide perovskite nanocrystals (NCs) have been recently rediscovered as possible alternatives to semiconductor quantum dots for electroluminescence (EL) devices and other light-emitting and sensing applications, and research into their basic photophysical properties is attracting increasing attention
We use nanocrystals of CsPbBr3 prepared by methods reported in literature
We first examined the influence of a surrounding matrix on their spectral properties and blinking behavior by dispersing the NCs in an inert matrix of PMMA and in a conductive matrix of PVK/PBD, both on the level of single NCs and aggregates of tens of NCs
