Growth and characteristics of Cr3+:YAG crystal fiber for fluorescence decay temperature sensor

Abstract: YAG crystal fibers with end Cr3+ doped have been grown by the laser heated pedestal growth method as the temperature sensor probe using fluorescence decay. The crystal fibers show good optical properties and mechanical strength and offer advantages of compact construction, high performance, and ability to withstand high temperature. The fluorescence characteristics of the Cr3+:YAG crystal fiber probe with temperature were investigated from −20to500°C. The experimental results indicate that Cr3+:YAG crystal fib… Show more

“…[1][2][3][4][5][6] Generally, optical parameters, such as the fluorescence intensity, the peak wavelength, the emission bandwidth, the fluorescence intensity ratio (FIR) as well as the fluorescence lifetime, can be adopted to detect temperature. [7][8][9][10][11][12] Unfortunately, the fluorescence intensity, the peak wavelength and the emission bandwidth are strongly affected by the external factor, such as light source, atmosphere and pressure. In contrast, FIR-based temperature sensors exhibit a high measurement accuracy and reliability because FIR is independent of spectral losses and fluctuations in the excitation density.…”

“…Therefore, it is quite meaningful to measure temperature with high spatial and temperature resolution. Recently, some efforts have been focused on the study of the temperature-dependent rare earth (RE) ions doped anti-Stokes (or upconversion, UC) emission or transition-metal (TM) ions doped Stokes emission material owing to their significant potential application in noncontact temperature sensors. Generally, optical parameters, such as the fluorescence intensity, the peak wavelength, the emission bandwidth, the fluorescence intensity ratio (FIR), as well as the fluorescence lifetime, can be adopted to detect temperature. Unfortunately, the fluorescence intensity, the peak wavelength, and the emission bandwidth are strongly affected by the external factor, such as light source, atmosphere, and pressure.

“…The fluorescence lifetime and fluorescence intensity of the material depends on the external temperature and generally have a linear relationship [ 46 ]. At present, two commonly used fluorescence high-temperature sensing schemes are available: one is the fluorescence lifetime (FL) method [ 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 ] and the other is the fluorescence intensity ratio (FIR) method [ 55 , 56 , 57 , 58 ].…”

“…Compared to single wavelength fluorescence intensity testing, the FIR method avoids the effects of light source intensity fluctuations. However, it suffers from some limitations in terms of performance, such as poor linearity between temperature and intensity [ 49 ]. On the other hand, the FL method does not require precise measurement of output light intensity and is not affected by fluctuations in light source intensity or external background noise, so it is widely used in commercial sensors.…”

“…Temperature ( T ) measurement is significant in both scientific and industrial fields. Recently, a novel noncontact temperature sensing technique, i.e., optical thermometry, has attracted considerable interests for its promising applications in electromagnetically and/or thermally harsh environments. In general, temperature-sensitive optical parameters, such as the fluorescence intensity, the emission bandwidth, the peak wavelength, the luminescence lifetime, and the fluorescence intensity ratio (FIR), can be used to detect temperature. Unfortunately, external factors including light source, atmosphere, and pressure have great impact on the fluorescence intensity, the emission bandwidth, and the peak wavelength.…”
