Abstract

Under 980 nm diode laser excitation, efficient upconversion emissions from the Ho³⁺/Yb³⁺ codoped CaWO₄ phosphor were obtained. The upconversion quantum efficiency was evaluated to be about 3.3% when the power density of the excitation laser was 47 W/cm². Additionally, temperature dependent blue emissions from the ⁵F _2,3/³K₈ and ⁵G₆/ ⁵F₁ states of Ho³⁺ ions were studied in the range of 303-923 K. The result demonstrated that using the ratio between the blue luminescence intensities of Ho³⁺ ions, the sensitivity and the accuracy for optical thermometry achieved here are superior to the previously reported Er³⁺ green fluorescence based optical temperature sensors.
