“…Mineral oils can be obtained from crude petroleum oil and are typically a mixture of large hydrocarbon compounds (composed of carbon and hydrogen only) and trace amounts of impurities containing-in addition to carbon and hydrogen-nitrogen, oxygen, sulfur, and some other elements [7]. There are two main classes of mineral oil used in industry: so-called paraffinic base oils, which have mainly C-C straight chains; and naphthenic base oils, which contain cyclic (aromatic) or linear (olefinic) non-saturated C=C double bonds [5].…”

“…Degradation of mineral oil (also known as aging) is defined as a slow irreversible change of the useful properties due to oxidation, hydrolysis or pyrolysis under the influence of the environment and thermocycling during their use [7]. Quantification of oil degradation is an important task related to various types of oils.…”

“…The main conclusion of those studies was that the observed coloration of the oils was not necessarily representative of significant deterioration of their properties and that UV-Vis spectroscopy or even a simple colorimetric approach allows, in principle, monitoring of the oxidation process [22]. The PL technique was applied for oil quality monitoring in several recent publications [7,12,22]. The authors mentioned, among other things, extremely high sensitivity and relative simplicity of the method.…”

We have studied photoluminescence (PL) properties of vacuum pump mineral oil as a function of the type and intensity of ionizing radiation exposure. The mineral oil has a simple aliphatic structure, which possesses no chromophore in the traditional sense. Unexpected PL in the mineral oil has characteristic features such as variation of the emission peak wavelength depending on the excitation wavelength and intensity dramatically increasing with radiation dose. The observed behavior can be understood in the framework of a previously suggested model introducing aggregation-induced PL and the formation of conjugated clusters comprising nontraditional chromophores. Our findings can be used for the development of optical sensors for real-time monitoring of oil utilized in vacuum pumps in nuclear fusion reactors.
