So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Lubin, Gur; Yaniv, Gili; Kazes, Miri; Ulku, Arin Can; Antolovic, Ivan Michel; Burri, Samuel; Bruschini, Claudio; Charbon, Edoardo; Yallapragada, Venkata Jayasurya; Oron, Dan researched the compound: Tri-n-octylphosphine Oxide( cas:78-50-2 ).Recommanded Product: 78-50-2.They published the article 《Resolving the Controversy in Biexciton Binding Energy of Cesium Lead Halide Perovskite Nanocrystals through Heralded Single-Particle Spectroscopy》 about this compound( cas:78-50-2 ) in ACS Nano. Keywords: biexciton cesium lead halide perovskite nanocrystal; SPAD arrays; biexciton binding energy; perovskite nanocrystals; quantum dots; single-particle spectroscopy. We’ll tell you more about this compound (cas:78-50-2).
Understanding exciton-exciton interaction in multiply excited nanocrystals is crucial to their utilization as functional materials. Yet, for lead halide perovskite nanocrystals, which are promising candidates for nanocrystal-based technologies, numerous contradicting values have been reported for the strength and sign of their exciton-exciton interaction. In this work, we unambiguously determine the biexciton binding energy in single cesium lead halide perovskite nanocrystals at room temperature This is enabled by the recently introduced single-photon avalanche diode array spectrometer, capable of temporally isolating biexciton-exciton emission cascades while retaining spectral resolution We demonstrate that CsPbBr3 nanocrystals feature an attractive exciton-exciton interaction, with a mean biexciton binding energy of 10 meV. For CsPbI3 nanocrystals, we observe a mean biexciton binding energy that is close to zero, and individual nanocrystals show either weakly attractive or weakly repulsive exciton-exciton interaction. We further show that, within ensembles of both materials, single-nanocrystal biexciton binding energies are correlated with the degree of charge-carrier confinement.
