In this study, transparent LaErZr2O7ceramic with high excess La and Er contents (nominally La1.28Er1.28Zr2O7.84) was successfully prepared by vacuum sintering at 1850 °C for 6 h using nanosized powder. The XRD, SEM, EDX and TEM results reveal that the single pyrochlore phase in the powder sample transforms to the coexistence of La-rich pyrochlore phase and Er-rich defect fluorite phase after high temperature sintering. The high excess amounts of La and Er favor the formation of pyrochlore structure. Despite the coexistence of two phases, the sample with 1 mm thickness shows excellent in-line transmittance in the visible to mid-infrared region (as high as 81% at 1100 nm). The upconversion and infrared emission under 980 nm exciting were measured and discussed as well.
