Abstrakt: Abstract—The kinetics of delayed fluorescence and phosphorescence of xanthene dyes in mouse tissues under the pulse-periodic excitation of molecules was studied in vivo and in vitro. The advantages of continuous monitoring of oxygen content in tissues by the kinetics of delayed fluorescence caused by singlet-triplet annihilation of singlet oxygen with triplet excitation of fluorophore are demonstrated. A method is proposed for determining the time of recovery of the concentration of oxygen consumed in tissues in vivo and in vitro during photodynamic processes. [ABSTRACT FROM AUTHOR]
