Paper Abstract

We studied up-conversion emission of triply doped (Ho,Tm,Yb):KLu(WO4)2 (KLuW) nanocrystals at the range of temperature 296-673 K at different excitation wavelengths. The intensity ratio between two emission lines was used for monitoring the temperature. Pumping Yb3+ at 980 nm provides a good response at relatively high temperatures, while pumping Tm3+ at 802 nm provides an excellent sensitivity in the biological range of temperatures., which make the material also attractive for biological temperature sensors.
