Abstract
Fluorescence intensity ratio thermometry based on hybrid -doped and -doped particles has been studied. We aim at overcoming the limitation that the relative sensitivity () 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 -doped and -doped particles constructs two emission bands with opposite temperature dependences. Furthermore, the makes a breakthrough by obtaining greater sensitivity in a high-temperature range; the maximum value obtained is at 633 K.
