Abstract

In this work, we present a comprehensive theoretical modelling of a chiral dimer made of two perovskite quantum dots (QDs). Taking into account the bright triplet exciton of QDs, we calculate the energies of the dimer’s quantum states and analyze the dependence of these energies on the dimer geometry. We also compute the circular dichroism (CD) spectra of the dimer and establish the optimal dimer parameters for maximizing its CD response. Our results show that the perovskite QD dimers feature a strong and tunable chiroptical response, making these superstructures attractive for chiral application.
