Abstract

Fluorescence intensity ratio thermometry based on hybrid Eu3+-doped GdVO4 and Cr3+-doped Al2O3 particles has been studied. We aim at overcoming the limitation that the relative sensitivity (Sr) decreases with the square of temperature owing to the thermal relation between the two emitting levels in one matrix in terms of the Boltzmann distribution law. The design of hybrid Eu3+-doped GdVO4 and Cr3+-doped Al2O3 particles constructs two emission bands with opposite temperature dependences. Furthermore, the Sr makes a breakthrough by obtaining greater sensitivity in a high-temperature range; the maximum value obtained is 1.4%K1 at 633 K.
