Abstract

The paper presents the results of experimental study of the singlet oxygen (¹&Dgr;O₂) lifetime in the solution, saturated by fullerene and oxygen in CCl₄ and irradiated by optical pump with various level of power and with various spectral content. It was shown that in the case of absence of the UV component in this optical pump, i.e. in the case using of only visible spectral range, the lifetime of ¹&Dgr;O₂ reaches ~ 50 ms for optical pump energy density of ~ 0/5 J/cm². Pulse duration was ~ 0.5-1 ms. Such criterion makes it possible to develop the outlook of the realistic singlet oxygen generator with optical pumping of fullerenes for pulse-repetitive and CW regimes of FOIL operation.
