Abstract:
Yb3+/Tm3+ codoped KLa(MoO4)2 phosphors are synthesized by a hydrothermal method. Under 980 nm excitation, the upconversion (UC) emission spectra of the phosphors are observed. The temperature sensing characteristic based on the fluorescence intensity ratio is studied. The maximum sensitivity reaches 2.93% K-1 at 453 K. The sensitivity value of non-thermally coupled levels is higher than that of thermally coupled levels. The results indicate that the KLa(MoO4)2:Yb3+/Tm3+ phosphor could be used in temperature sensors.
