Phosphorescence of Liquid Oxygen Excited at Cooperative Transitions in the Visible Spectral Region

Phosphorescence of liquid oxygen under excitation at cooperative transitions of О 2 –О 2 molecular oxygen complexes is studied using direct optical excitation by LED arrays emitting in the near-UV and visible spectral regions at wavelengths partially or completely coinciding with the absorption line...
