“…The fabrication of oxygen sensors is as shown in the scheme: the prepared SiO 2 /Au NPs were uniformly mixed with PtTFPP dyes and composite sol–gel solution; then, the glass slides were immersed in the mixture and dried. There are many good polymer matrices used in oxygen sensors, including polydimethylsiloxane, ethyl cellulose, and hydroxymethyl cellulose. ,− We just selected the sol–gel in Chu’s report to fabricate PtTFPP-based oxygen sensors and investigate the emission enhancement of SiO 2 /Au NPs. Oxygen sensors without matrices were prepared with ethanol instead of the sol–gel solution.…”

In the vicinity of metal nanostructures, phosphorescent intensity can be greatly enhanced through the localized surface plasmon resonance (LSPR). The enhancement of phosphorescence intensity in noble-metal nanoparticle (NP) systems is highly dependent on the overlap of the absorbance peak of a noble metal with that of phosphorescent dyes. When the peak of the NPs' absorption spectra has a maximum overlap with that of these dyes, the phosphorescence enhancement is the largest. Here, we use a seeded growth method to synthesize SiO 2 / Au NPs with tunable plasmonic resonance and compare their phosphorescence enhancement for an oxygen range of 0−21%. The measurement sensitivity of oxygen is strongly dependent on the enhancement of phosphorescence. When used with PtTFPP, when the absorbance peak of the SiO 2 /Au NPs has a maximum overlap with that of PtTFPP, the phosphorescence enhancement factor is as high as 7; the sensitivity of oxygen concentration is as high as 75. Moreover, we also optimize the performance by varying the number of NPs to eliminate the nonradiative energy-transfer (NRET) process and self-quenching.

“…Pressure-sensitive paints are mainly composed of oxygen probes, a polymer substrate, a binder and solvent. [19][20][21] There are three main methods for preparing PSPs. 22 The most widely used one is the physical doping method that mixes oxygen probe molecules into polymer materials, [23][24][25] because of its simplicity and convenience.…”

Pressure-sensitive paints (PSPs) have been demonstrated to be very important for aerodynamics research. In order to improve the pressure sensitivity and adhesion ability of PSP, herein, a series of fluorine-containing copolymers compositing of an oxygen and pressure-responsive probe derived from platinum(II)- 5,10,15,20-tetrakis-(2,3,4,5,6-pentafluorophenyl)-porphyrin (PtTF-PP) named as poly[(tBs) a -co-(TFEM) b -co-(PtTFPP-1MA) c ] were synthesized and investigated as PSPs. These PSPs were constructed with different fluorine ratios for the investigation of the effect of fluorine contents on PSPs. Especially, PSP (F 0.33 ) with the trifluoroethyl methacrylate (TFEM) molar ratio of 33% in the copolymers could adhere well to the surface of an aircraft model. F 0.33 showed high oxygen sensitivity (I 0 /I 100 = 32.87), reasonable response time to oxygen (44 s), high pressure sensitivity (S P = 0.75%/kPa at 20 C) and low temperature response (S T = À0.77%/ C at 100 kPa). F 0.33 was further sprayed on the surface of a delta wing of an aircraft model and its pressure response was verified in a wind tunnel. The data from F 0.33 film at the same wind speed and position were close to the pressure data measured by using traditional method using open pressure holes, showing the potential application of these PSPs.

“…The content of dissolved oxygen in water is an important indicator to evaluate the deterioration of water quality [ [6] , [7] , [8] ] . In meteorological measurement, the pressure distribution of each measuring point at the same height can be calculated by measuring the oxygen partial pressure [ 9 , 10 ], which provides a basis for weather forecast. With the progress of science and technology, the standard of oxygen detection has also been improved.…”
