Er3+and Yb3+codoped Gd2Mo4O15upconversion (UC) phosphors are synthesized by high temperature solid state reaction. The crystalline phase and morphology are studied in detail by X-ray diffraction (XRD), Raman spectroscopy and scanning electron microscopy (SEM). Under 980 nm laser excitation, the phosphors show a significant green UC luminescence contributed from2H11/2/4S3/2→4I15/2transitions of Er3+, while the popular red4F9/2→4I15/2emission is quite weak. The temporal evolutions of Er3+and Yb3+emissions after 980 nm pulse excitation are studied as a function of Er3+and Yb3+concentrations. It is revealed that the weak red UC emission is due to its low emission efficiency in Gd2Mo4O15that has a high cutoff phonon energy of 960 cm−1. The temperature sensing behaviors based on the thermally coupled2H11/2and4S3/2levels have been explored. A high absolute sensitivity of 0.00853 K−1at 554 K is achieved and an excellent thermal durability is observed. The relative absorptance of4I15/2→2H11/2transition to the4I15/2→4S3/2transition is proposed as a good measure for evaluating the absolute sensitivity based on the comparative study of some familiar materials. Our results imply that Gd2Mo4O15is a promising green UC phosphor for optical thermometry.
