20.500.12556/RUL-190820 Eksperimentalna primerjava termografskih fosforjev za merjenje temperature na osnovi luminiscencnega upada Experimental comparison of thermographic phosphors for temperature measurement based on luminescence decay Four thermographic phosphors, QMK24/N-C7, QMK66/F-A1, MK24/F-X and EQD25/F-U1, were applied to brass substrates using an inorganic Ceramabind 643-2 binder. A thin brush coating and a syringe-applied coating were compared. The samples were spectrally characterized under 405 nm and 365 nm excitation and tested in an automated dual-channel phosphor-thermometry system with detection near 635 nm and 660 nm. Only QMK24/N-C7 and EQD25/F-U1 provided a sufficient signalto-noise ratio for stable exponential fitting at several temperatures. Values digitized from the recorded plots indicate sensitivities from −15, 6 to −20, 1 µs/ ◦C for QMK24/N-C7 and from −7, 8 to −8, 4 µs/ ◦C for EQD25/FU1. QMK24/N-C7 was nominally more sensitive, while EQD25/F-U1 produced higher SNR and therefore more repeatable temperature characteristics. The results show that spectral matching, coating thickness and coating homogeneity must be considered together when selecting a phosphor for a practical measurement system. termografski fosfor čas upada merjenje temperature thermographic phosphor decay time temperature measurement true false true Slovenski jezik Angleški jezik Neznano 2026-11-04 13:54:20 2026-11-04 13:54:22 2026-11-06 04:29:28 0000-00-00 00:00:00 2026 0 0 Str. 353-356 0000-00-00 NiDoloceno Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.317 2591-0442 293090819 292311811 RAZ_Semelbauer_Klemen_2026.pdf RAZ_Semelbauer_Klemen_2026.pdf 1 E59FF2564B6C403E9717209C07882CA4 1084bb1ba93dd9fcb02a82d547d9d68c1f5afbc370da45c5fd8bb334f2702c67 cb20484a-d84e-11f1-aea2-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=252491 https://erk.fe.uni-lj.si/2026/papers/semelbauer(eksperimentalna_primerjava).pdf 0 d9a8afbd-d84e-11f1-aea2-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=252492 Fakulteta za elektrotehniko 0 0 0
