When blinking helps: enhanced single-photon purity in the off states of perovskite quantum dots
Adam Olejniczak, Jehyeok Ryu, Francesco Di Stasio +2
Photoluminescence blinking typically degrades the single-photon purity of quantum dot emission. Here, we show that individual CsPbBr perovskite quantum dots (PQDs) can exhibit…

Size-dependent Dielectric Permittivity of Perovskite Nanocrystals
Jehyeok Ryu, Victor Krivenkov, Vitaly Goryashko +2
Perovskite nanocrystals (PNCs) are promising building blocks for quantum photonic devices. Optical properties of PNCs can be enhanced by integration with optical cavities or nanoan…
