Research paperExperimental CharacterizationExcitation lifetime extracted from electron-photon (EELS-CL) nanosecond-scale temporal coincidencesNadezda Varkentina, Yves Auad, Steffi Y. Woo, Florian Castioni et al.arXiv preprint·2023·10.48550/arxiv.2306.15372·arXiv:2306.15372AbstractElectron-photon temporal correlations in electron energy loss (EELS) and cathodoluminescence (CL) spectroscopies are used to measure excitation decay times and their dependence on excitation energy. The method is demonstrated on nanodiamonds with NV₀ defects and on h-BN with 4.1 eV defects. Transition radiation is used to estimate the instrumental response function, found to be typically about 2 ns. The measured lifetimes of NV₀ centers in diamond nanoparticles and 4.1 eV defects in h-BN agree with previous reports.Read more
