Abstract
The influence of cerium oxide nanoparticles on singlet oxygen generation upon photosensitizer irradiation was studied. Solutions of tetra-15-crown-5-phthalocyanines (aluminium(III), gallium(III) and indium(III) hydroxide, 1Al, 1Ga, 1In) in DMSO were used as photosensitizers.Ceria nanoparticles (CNPs) were shown to inhibit the photobleaching process of the crown-phthalocyanines induced by UV and visible irradiation of these photosensitizers. The photoprotective properties of CNPs were shown to depend on their size and lattice parameter, with these in turn being determined by conditions of CNPs’ synthesis. In addition, the deactivation of the reactive oxygen species and the UV-shielding effect of ceria nanoparticles were demonstrated.
