Mechanism of the preventive effects (How it works):
In the presence of ultraviolet light, molecules of microorganisms are entrapped and exposed to the action of the energy of free electron holes with electron energy of 3.2 eV. This energy is greater than the energy of most bonds between atoms in molecules of organic substances. Consequently, these bonds are broken and their place binds atmospheric oxygen. As can be seen from and experiment a factory smoking area (Figure 2), where the ceiling plate was illuminated by fluorescent UVA, all the smoke and deposits on the active layer decomposed.
