Abstract By co-doping Yb3+/Er3+ into ordinary material In2O3, the up-conversion glow behavior will be triggered up. On this basis, the luminescence intensity can be significantly improved by tri-doping Zn2+ ions. Compared with In2O3:Yb3+/Er3+, the luminescence intensity of In2O3:Yb3+/Er3+/Zn2+ is significantly enhanced and the emitting light changes from faint red to bright green. This can be attributed to the reduction of site symmetry of the luminescence center and the promotion of crystallinity because of lattice distortion caused by Zn2+ ions. The up-conversion luminescence of the In2O3:Yb3+/Er3+/Zn2+ in the red and green light regions are two-photon excitation process, and the quantum yield (QY) is calculated to be 0.1%. The luminescence at the 524 nm emission peak corresponds to the transition Er3+:2H11/2 → 4I15/2. Other two emission peaks in green area (550 nm, 564 nm) correspond to the transition Er3+:4S3/2 → 4I15/2. And the emission peaks in red area (659 nm, 683 nm) root in the transition Er3+:4F9/2 → 4I15/2.

通过三掺杂 Zn2+ 增强 In2O3:Yb3+/Er3+ 中的绿色上转换发光

摘要 通过将Yb3+/Er3+共掺杂到普通材料In2O3中，会触发上转换发光行为。在此基础上，三掺杂Zn2+离子可以显着提高发光强度。与In2O3:Yb3+/Er3+相比，In2O3:Yb3+/Er3+/Zn2+的发光强度显着增强，发光由暗红色变为亮绿色。这可归因于发光中心位置对称性的降低和由于 Zn2+ 离子引起的晶格畸变而促进结晶度。In2O3:Yb3+/Er3+/Zn2+在红光和绿光区的上转换发光为双光子激发过程，计算量子产率(QY)为0.1%。524 nm 发射峰处的发光对应于转变 Er3+:2H11/2 → 4I15/2。绿色区域中的其他两个发射峰 (550 nm, 564 nm) 对应于过渡 Er3+:4S3/2 → 4I15/2。红色区域（659 nm、683 nm）的发射峰根植于过渡区 Er3+:4F9/2 → 4I15/2。
