摘要：
Fluorescence spectroscopy has been investigated to determine its suitability for condition monitoring of oxidized polyphenyl ether lubricants. Oxidative degradation of the lubricant was shown to induce specific changes in its fluorescence properties. Excitation/emission wavelengths with monitoring potential were identified and were found to yield a useful correlation between emission intensity and viscosity increases of the degraded lubricant for two different formulations. Application of this technique on neat thin films of the degraded fluids yields similar correlations.
