论文部分内容阅读

Three-dimensionally ordered macroporous (3DOM) La2O3 co-doped of Er3+ and Yb3+ nanomaterials were prepared by PMMA template-assisted method1, 2, and characterized by the XRD, SEM, TEM and up-conversion luminescence spectra.When the 3DOM La2O3:Er/Yb nanoparticles were excited by a continuous wave laser in the near-infrared at 980 nm at room temperature, there are two up-conversion luminescence emission peaks located in the range of 530-560 nm (green light) and 650-675 nm (red light), and the ratio of the intensity of green light/red light is about 1 : 2.2.
