“…As shown in Figure 5b, the linear dynamic response ranges only covered the scope between 0 and 6 mg/L However, for the Ag NPs-doped sensor, it was observed that the calibration curve became linear and the response ranges were enhanced for 0–15 mg/L. This is due to the spectral consequences considering absorption characteristics of the Ag NPs [34], and the function of Ru(DPP) 3 Cl 2 undergoing a metal-to-ligand charge-transfer (MLCT) electronic transition. The emission from the Ru(DPP) 3 Cl 2 was located at a peak wavelength of 608 nm (in PMMA), which overlaps with the absorption of Ag NPs.…”

“…Vamsi K studied the effect of different sizes of silver and gold nanoparticles on the fluorescence properties of three kinds of ruthenium complex [33]. In recent years, fibers doped with silver nanoparticles by electrospinning technique was investigated, and the results showed that the sensitivity and linear calibration plots could be tuned by doping with gold or silver particles [34]. However, those reported works of nano-fiber-based sensing films are limited to the lifetime approaches [35].…”

A ratiometric optical sensor has been developed with electrospinning processing method for dissolved oxygen measurement. The sensing film is fabricated by using silver nano-particles (Ag NPs) doped with tris(4,7-diphenyl-1,10-phenanthroline) ruthenium(II) dichloride complex (Ru(DPP)3Cl2) encapsulated in plasticized polymethyl methacrylate (PMMA). An insensitive 3-(2-benzothiazolyl)-7-(diethy lamino)-(6CI,7CI) (Coumarin6) is adopted as reference. The ratio of oxygenation is calculated at each image pixel of a 3CCD camera to quantify the oxygen concentration in aqueous environment. Compared to Ag-free film, the response time of Ag-containing films were improved from 1.5 s to 1.0 s upon switching from deoxygenated to air saturation and from 65 s to 45 s from air saturation to fully deoxygenated. The response times of the Ag-free film obtained by knifing was 2.0 s upon switching from deoxygenated to air saturation and 104 s from air saturation to fully deoxygenated. Results of the evaluation of accuracy, limit of detection, stability, and photostability are presented. An experiment measuring the spatiotemporal variation of oxygen distribution within the photosynthesis and respiration of Chlorella vulgaris is demonstrated. It is shown that the nanofiber-based optical sensor film could serve as a promising method for rapid oxygen monitoring in aqueous applications.

“…For the detection of oxygen, the fluorescent tris (2,2′-bipyridyl) ruthenium(II) chloride [Ru(bpy)3] 2+ dye embedded in polymeric electrospun mats together with hydrophilic and hydrophobic ionic liquids were used and the offered composites provided higher sensitivity for oxygen and extraordinary long term stability [18]. The oxygen-induced response of the Ru(bipy)32 utilization of AgNPs and ILs resulted in many advantages such as increment in oxygen sensitivity and all sensor dynamics, linear calibration plot for larger concentration ranges [21]. Recently, utilizing some of the metal oxides as an additive improve the performance of gas sensors, such as stability, sensitivity, linear working range, the limit of detection and quantification.…”

In this study, we measured oxygen-induced emission and decaytime data of tris(2,2′-bipyridyl)ruthenium(II) chloride dye in the presence of additives, maghemite and ionic liquid, 1-butyl-3methylimidazolium tetrafluoroborate. The fluorescent dye along with the additives was embedded in ethylcellulose matrix that was used as supporting material in form of thin-film and electrospun mat. The synthesized maghemite was used to enhance the oxygen sensitivity and linear working range of the dye. Ionic liquid (IL) was used to increase the stability and sensitivity of the sensing fluorophore. Together with the additives ruthenium dye-based composites exhibited higher Stern-Volmer constant (KSV), relative signal change and larger linear response. High relative signal change and KSV values mean that fluorophore has a better oxygen gas sensitivity.Stern-Volmer values of thin-film and microporous mats were found 1.64×10 −2 and 2.21×10 −2 , the relative signal changes (I0/I) were calculated as 2.64 and 3.21, respectively. There is no previous work about the utilization of both maghemite and ionic liquid additives together for the enhancement of oxygen sensitivity of the ruthenium.
