CsPbBr<sub>3 </sub>Perovskite Quantum Dots as Single Photon Sources

ORAL

Abstract

Cesium Lead Bromide (CsPbBr3) Perovskites Quantum Dots (PQDs) are zero-dimensional semiconducting particles with tunable optical properties. We are interested in PQDs as possible single photon sources with applications in quantum computing and quantum cryptography. We have successfully fabricated CsPbBr3 PQDs and measured their photoluminescence intensity as a function of wavelength. As temperature is varied from 77K to 293K, the central wavelength undergoes a blue-shift. The fabricated CsPbBr3 PQDs are stable at 77K and 293K. Diluting the solution used in fabrication should allow us to create samples of individual, spatially-resolved quantum dots, which can then be verified with g(2) measurements.
