On the possibility of realizing the singlet oxygen generator on the base of optically pumped fullerenes and of fullerene-like nanoparticles

We present the experimental results on singlet oxygen generation via interaction of pumping photons (laser or lamp light), fullerenes (or fullerene-like nanoparticles - astralens) and oxygen in solid-state structures, in solutions and in suspensions. It was shown that the singlet oxygen is adsorbed by the solid-state fullerene coating and by powder-like astralen. It was shown that in course of evaporation of the solution (due to the pump action) is observed the singlet oxygen extraction to the gaseous phase, and the lifetime of 1ΔO2 grows significantly.© (2003) COPYRIGHT SPIE--The International Society for Optical Engineering.
