I Fluorescence from core shell quantum dots

  1. Nov 13, 2017 #1
    What is the reason for enhancement in the intensity of emission due to the introduction of a shell in quantum dots? I do understand the blue shift in quantum dots but how does a shell enhance it?

    tl;dr: Quantum dots can interact with their surroundings to provide non-radiative pathways for exciton decay. Shells reduce these interactions, increasing the quantum yield of the dots.
