Lu 2 O 3 doped Nd: YAG transparent ceramics were prepared by solid-state reaction and vacuum sintering. Ionic size compensation was investigated by comparing the X-ray diffraction patterns (XRD) and Raman spectroscopy (Raman) of (Nd 0.06 Lu x Y 2.94-x ) 3 Al 5 O 12 ceramics. The micrographs and element mappings of ceramics samples sintered at 1750°C for 50 h were analyzed by scanning electron microscope (SEM) and X-ray energy dispersive spectroscopy (EDS), respectively. The emission peak intensity of 1064 nm is the largest, which corresponds to the 4 F 3/2 → 4 I 11/2 transition of Nd 3+ . Fluorescence spectra and decay curves show that the fluorescence intensity was the highest when the concentration of Lu 2 O 3 was 0.02, and the fluorescence lifetime was 193.92 µs. The elimination of lattice distortion is beneficial to the improvement of fluorescence properties, which can be attributed to ionic size compensation of Lu 3+ .
