Spontaneous transitions to enhanced fluorescence for GeV centers in a single microcrystalline diamond

Autor: Lozing Natalia A., Gladush Maxim G., Eremchev Ivan Yu., Ekimov Eugeniy A., Naumov Andrey V.

Publikováno v: EPJ Web of Conferences, Vol 190, p 04012 (2018)

We propose a theoretical explanation of spontaneous transitions between dim and bright fluorescence intensity states observed experimentally in a microcrystal of diamond with germanium-vacancy colour centres driven by a continuous wave laser. We use

The question of the axial coordinate determination accuracy is quite sophisticated in far field 3D fluorescence nanoscopy. The accuracy of a point emitter axial coordinate reconstruction depends among other things on the conversion efficiency of the

Contribution of electron-phonon coupling to the luminescence spectra of single colloidal quantum dots

Autor: Podshivaylov, Eduard A., Kniazeva, Maria A., Gorshelev, Aleksei A., Eremchev, Ivan Yu., Naumov, Andrei V., Frantsuzov, Pavel A.

Publikováno v: Journal of Chemical Physics 151 (2019) 174710

Luminescence spectroscopy experiments were realized for single colloidal quantum dots CdSe/ZnS in a broad temperature range above room temperature in a nitrogen atmosphere. Broadening and shifts of spectra due to the temperature change as well as due
