The model of a fiber optic sensor device which operational principle is based on the thermal quenching of luminescence for ambient temperature measurements was experimentally studied. The construction of a multimode optical fiber with a transmission of more than 90%/m in the spectral region from 350 to 650 nm and a quartz capillary filled with a photoactive polymer composition based on epoxyacrylate and the europium complex with 2-naphthoyltrifluoroacetone and trioctylphosphinoxide was used as a sensitive sensor element. An exponentially decreasing character of the temperature dependence of the luminescence intensity was discovered for the photoactive composition incorporated into the sensor (excitation wavelength, 355 nm; luminescence wavelength, 615 nm) within a range from 20 to 100°C. A quasi-linear change in the luminescence intensity depending on the power of the launched UV radiation was determined.
