    Abstract

    Ho3+/Yb3+: BaMoO4 phosphors with different concentrations were fabricated by a gel combustion method. The upconversion (UC) luminescence, intrinsic optical bistability, and the corresponding mechanisms were reported for the present system. The optical thermometric properties based on red (5F55I8) and green (5F4/5S25I8) emissions were studied. The sensing sensitivities could be tuned by manipulating the cooperative energy transfer process. The highest absolute sensitivity was 99 × 10 4 K 1 at 573 K, which is larger than that of many previous UC materials.
