چکیده انگلیسی
Structural and luminescence properties of uncovered YVO4:Nd3+ and core-shell YVO4:Nd3+@SiO2 nanoparticles synthesized via modified Pechini technique were studied. Effect of silica shell thickness on steady state and kinetics luminescence parameters was investigated. Synthesized nanoparticles were used as non-contact optical thermometers operating in the second biological window upon heating-free 808Â nm light by monitoring fluorescence intensity ratio between Nd3+ emission bands as a temperature-dependent parameter. Benefits of silica coating on the temperature sensing properties were clearly demonstrated. The best thermal sensitivity was found to be 0.40% Kâ1 at 299Â K, the minimum temperature uncertainty was less than 0.5Â K, which is enough for accurate temperature evaluation in the real systems.
