Quantum trajectories of the photoluminescence of F 2 centers in a LiF crystal

Fluorescence Intensity Time Trajectories of F2 Centers in LiF Crystal

“…Fig. 1(a, b) [2,3] shows fragments of the luminescence intensity trajectories of a single F2 center. The term "intensity trajectory" is understood as the time dependence of the luminescence intensity of a single-color center at constant excitation.…”

“…The term "intensity trajectory" is understood as the time dependence of the luminescence intensity of a single-color center at constant excitation. The authors of [1][2][3][4] call these trajectories quantum trajectories of the photoluminescence of the F2 center. Figure1b.…”

“…Figure1b. Experimentally recorded intensity trajectories of F2 center in a LiF crystal subjected to excitation by the second harmonic of a neodymium laser [3].…”

“…Single-molecule spectroscopy (SMS)has been developing for over 30 years and has great interest to scientists working in the fields of chemistry, physics, biology and medicine. Not much research on fluorescence of a single impurity molecules and color centers in solids and transparent crystals are known, for example [1][2][3][4].…”

“…The authors of [1][2][3][4] believe that they observe the luminescence of single F2 centers; however, their conclusions are based on not fully substantiated assumptions. In this paper, the authors consider it necessary to make some comments that will help to come to more realistic conclusions.…”
