N2 - The damage to human body caused by laser and ultraviolet light from electronic products and sunlight has attracted attention. In this paper, on the basis of previous work, the near-infrared absorbing powder Er4Al2O9 was prepared by a more straightforward co-precipitation method, and intended to apply on laser protection. To achieve compatible absorption at 1064 and 1540 nm, the effects of doping Sm3+ and Dy3+ on the phase composition and reflectivity were inquired. The morphology, phase composition and reflectance of the fines were characterized by X-ray diffraction, Scanning Electron Microscopy and the ultraviolet-visible spectrophotometer (UV3600PC). No significant variation on the crystal structure was found of doped Sm3+ and Dy3+. While, the introduction of Sm3+/Dy3+ could greatly change the morphology of Er4Al2O9 powder, which will further affect the reflectivity performance. Through the co-doping of Sm3+ and Dy3+, it is expected to further broaden the characteristic absorption peak at 1100 nm. The results show that the absorption peak of Sm3+ at 1100 nm could be broadened with the increase of Dy3+ doping amount, and the reflectivity of Er0.8Dy2.0Sm1.6Al2O9 at 1064 and 1540 nm reaches the lowest value. Compared with the ordinary un-doped powder, the reflectivity of the co-doped powder at 1064 nm decreased by 26.41%, indicating a good application prospect.
