It was found that the obtained material exhibits an intense green emission (510–560 nm) both via up-conversion (excited by 975 nm) and down-conversion (excited by 379 nm), which depend on the Mo6+ contents. Particularly, compared with the free-Mo6+ sample, the green emission intensities of the samples doped with 5% Mo6+ mol are 50 and 35 times higher for UC and DC emissions, respectively. Furthermore, the temperature sensing property of the HA/β-TCP: Er-Yb-Mo composite is investigated by fluorescence intensity ratio (FIR) technique, showing a high and competitive sensitivity with a maximum value of 0.0064 K−1 at 403 K. The results indicated that the HA/β-TCP: Er-Yb-Mo phosphor can be useful for high-temperature-sensing applications. 2021-06-15T07:40:38Z 2021-06-15T07:40:38Z 2021 Article Working Paper https://www.sciencedirect.com/science/article/abs/pii/S0925838821008926?via%3Dihub#! https://dlib.phenikaa-uni.edu.vn/handle/PNK/1775 Journal of Alloys and Compounds en Journal of Alloys and Compounds |
