The TSP measurement is often used in wind tunnel tests to measure the temperature and flow fields in the aerodynamic field. The measurement accuracy is affected by the characteristics of TSP, such as temperature sensitivity, pressure dependency, luminescent intensity, photostability, and surface condition. The characteristics depend on the formulation of TSP. This study investigates the characteristics of the TSP using dichlorotris (1,10-phenanthroline) ruthenium(II) hydrate (Ru-phen). We compare the characteristics of TSPs using different polymers, solvents, and dye concentrations. The TSPs using polyacrylic acid as a polymer shows linear calibration curves, high luminescent intensity, high photostability, and smooth surface. On the other hand, the TSPs using polymethyl methacrylate have nonlinear calibration curves, low luminescent intensity, strong photodegradation, and a rough surface.<\/jats:p>","DOI":"10.3390\/s22030901","type":"journal-article","created":{"date-parts":[[2022,1,25]],"date-time":"2022-01-25T21:07:11Z","timestamp":1643144831000},"page":"901","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Influence of Formulations on Characteristics of Ruthenium-Based Temperature-Sensitive Paints"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6423-3394","authenticated-orcid":false,"given":"Tsubasa","family":"Ikami","sequence":"first","affiliation":[{"name":"Institute of Fluid Science, Tohoku University, Sendai 980-8577, Japan"},{"name":"Department of Aerospace Engineering, Tohoku University, Sendai 980-8579, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8143-7321","authenticated-orcid":false,"given":"Koji","family":"Fujita","sequence":"additional","affiliation":[{"name":"Institute of Fluid Science, Tohoku University, Sendai 980-8577, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1480-3037","authenticated-orcid":false,"given":"Hiroki","family":"Nagai","sequence":"additional","affiliation":[{"name":"Institute of Fluid Science, Tohoku University, Sendai 980-8577, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Liu, T., Sullivan, J.P., Asai, K., Klein, C., and Egami, Y.
