摘要：
Up-conversion phosphors have attracted considerable attention for their visible-light emission. In this study, a ZnO-TiO2 up-conversion phosphor containing Yb3+ and Er3+ ions was prepared; its emission characteristics and crystal structure were analyzed, and its nanoscale elemental mapping was examined. The metal organic decomposition (MOD) method was used to fabricate the samples. After firing the sample at 1000 degrees C, the emission intensity showed a maximum when the molar ratio was Ti/Zn/Yb/Er = 1/1/0.06/0.02. Finally, the function of each element was considered from the viewpoint of the crystal structure and nanoscale mapping.
