摘要

In this paper, a novel upconversion phosphor is reported. Based onXRDand EDS, it is confirmed that the phosphor is monoclinic Gd2Mo4O15:Yb3+, Ho3+ with P21/c space group. The non-radiation decay of I-5(6) to I-5(7) dominants the depopulation of I-5(6), thus the phosphor produces the red upconversion emission with high emission intensity and good color quality, and shows the favorable temperature sensing property. When using non-continuous excitation mode, the temperature sensitivity is determined as 0.0452 K-1. Because the sensitivity is the same at any temperature, the new upconversion material may have greater potential for temperature sensing application than Er3+ doped upconverison materials.
