Light Emitted from a Liquid that Flows in a Narrow Channel as Triboluminescence

摘要: The flow of a liquid through narrow channel under high pressure (on the order tens atmospheres) can be accompanied by emission light, which has been termed hydroluminescence. We have shown that this light takes place both from gas and phase, with each type being characterized its own radiation spectrum. spectra hydroluminescence are similar to photoluminescence obtained upon UV irradiation study. Therefore, is not specific type; only one ways excitation emission, which, in case, caused friction. In other words, hydrodynamic luminescence referred wider class phenomena—triboluminescence.
