Silicon nanoparticle photophysics and singlet oxygen generation

The effect of molecular oxygen and water on the blue photoluminescence of silicon nanoparticles synthesized by anodic oxidation of silicon wafers and surface functionalized with 2-methyl 2-propenoic acid methyl ester is investigated. The particles of 3 ± 1 nm diameter and a surface composition of Si...
