“…As to the luminescence spectrum of YAG nanocrystals doped with Yb3+ ions, it contains the main emission band with a maximum at wavelength of 1030 nm and an additional one at wavelength of 1050 nm which are specific to Yb3+ ions in YAG matrices. These bands correspond to the F5/24→I7/24 electronic transition 20 …”

“…YAG nanocrystalline powders can be synthesized via different liquid-phase methods, such as polymer-salt method, 20 co-precipitation, 28 sol-gel method, 29 and combustion synthesis 30 . In this work, the modified Pechini method, a modification of the Pechini sol-gel method, was applied for fabrication of YAG nanocrystalline powders, which are the principal components of a luminescent temperature sensor.…”

.We developed and characterized luminescent temperature sensors with a simple construction based on YAG : Ln3 + (Ln = Nd, Yb, Ce) nanocrystals and silica multimode optical fibers. Lanthanide-doped nanocrystals 40 to 60 nm in size were synthesized in the form of powders using the modified Pechini method. The obtained materials exhibited high sensitivity of luminescence intensity to temperature variations at wavelengths of 550 nm (YAG : Ce3 + ), 1030 nm (YAG : Yb3 + ), and 1064 nm (YAG : Nd3 + ) in the temperature range 50°C to 600°C. Additionally, we offered a method to eliminate influence of vibration on accuracy of temperature measurements by adding SiO2 sol to powders after their synthesis in sensitive elements.
