High-sensitivity optical thermometer based on the luminescence of divalent and trivalent thulium ions in CaAl<sub>4</sub>O<sub>7</sub>:Tm<sup>2+/3+</sup> operating in cryogenic and high temperature ranges
The material CaAl 4 O 7 :Tm 2+/3+ showed an optimal relative sensitivity from cryogenic to high temperatures. A gradual change in emission color was observed in CIE diagram with varying temperatures.
