“…Corresponding data for fused silica are also reported for the sake of comparison, as it is today one of the preferred material for microfluidic devices, especially in hostile environment. While its resistance to chemicals is excellent, γ-irradiated fused silica displays intense coloration (darkening), which is well reported in the literature [20,21].…”

The use of microfluidics technology and the miniaturization of analytical techniques is of high interest for the chemical and nuclear industries. In the latter, the reduction of effluents deriving from actinides concentration monitoring along R&D and pilot-scale purification processes is a permanent concern. lndeed, the extremely harsh operation conditions limit the imple mentation of standard analytical techniques and methodologies, and in this regard, the use of spectrophotometric techniques for effluents characterization becomes advantageous in terms of robustness, implementation and sensitivity at the microfluidic scale. In this work, we report a study of the effect of exposure to different chemicals used in hydrometallurgical processes, and to gamma radiation typical of the Plutonium and Uranium Refining by Extraction process, on the optical and structural properties of different polymeric materials commonly used for the fabrication of microfluidic and optofluidic systems. This study shows that low-cost castable and/or engravable materials (e.g. polydimethylsiloxane and poly-methyl methacrylate) are ideal for the study and development of Photonic Lab on a Chip systems that will be used in a nuclear environment.

“…The structural defects in fused silica mainly included dislocations, ODC, colo r centers, etc. Balizakas proposed a damage model for optics under high-power laser irrad iation, and pointed out that when color centers accumulate to a certain concentration, laser damage will appear on the optical surface [13][14][15][16]. Ye found that ODC and NBOHC may be the main defects that induce laser damage [17].…”

Fused silica, as an excellent optical material, was widely used in the fabrication of laser optics applied in short-pulse/high-power laser systems. Fused silica containing structural defects was easy to be destroyed under laser irradiation. Deeply understanding the impact of different structural defects on the damage characteristics was of great significance for improving the laser damage threshold of fused silica optics. This work focused on structural defects including Oxygen Deficiency Center (ODC), Non-Bridging Oxygen Hole Center (NBOHC), E’ center, Peroxy Linkage (POL), Peroxy Radical (PDR), and elaborated on its formation laws in detail. The changes of damage characteristics and optical property of fused silica with different structural defects were calculated by first principle method. Taking E’ center defect as example, the band gap of defective silica was 3.1242 eV while that of β silica was 5.61 eV, which meant that electrons were more likely to cross the band gap under laser irradiation, led to electron avalanche and induced laser damage. Meanwhile, the optical properties of fused silica with different structural defects also showed significant difference. The reflectivity of β silica was 0.045, while that of silica with E’ center defects was 0.0715. Under 355nm laser irradiation, the absorption of β silica was 0 cm-1 while that of E’ center defects was 16600 cm-1, the absorptivity increased significantly. The change of optical properties also increased the probability of laser damage. In this work, certain support could be provided for the laser-damage theory of fused silica, and the relevant results could also provide important reference for suppression of structural defects.
