Abstract The photoluminescence modification of rare earth ions base on the photonic band gap engineering was extensively reported. In this work, the effect of up-converting luminescence suppression of Er3+ on the near infrared luminescence and cooperative energy transfer from Er3+ to Yb3+ was investigated in the YbPO4 inverse opals single-doped with Er3+ and co-doped with Nd3+ and Er3+. For the YbPO4:Er3+ inverse opals, when the photonic band gap is overlapped with the green or red up-converting luminescence of Er3+, the green or red up-converting luminescence of Er3+ was suppressed in the YbPO4:Er3+ inverse opals upon the 980 nm excitation, respectively. It is significative that the enhancement of near infrared luminescence of Er3+ was observed, which is attributed to the electron redistribution in the excited energy levels caused by the upconversion luminescence suppression in the YbPO4:Er3+ inverse opals. For the YbPO4:Nd3+,Er3+ inverse opals, the green upconversion and near infrared luminescence of Er3+ and the near infrared luminescence of Yb3+ were observed excited at 808 nm. The near infrared luminescence enhancement of Yb3+ was obtained due to the cooperative energy transfer enhancement from Er3+ to Yb3+ caused by the green upconversion luminescence suppression. The result is helpful to learn the relationship between upconversion and infrared luminescence in rare earth ions doped materials.

上转换发光修饰对 YbPO 4 :Er 3+ , Nb 3+ /Er 3+ 反蛋白石中近红外发光和协同能量转移的影响 在 980 或 808 nm 激发

摘要 基于光子带隙工程的稀土离子光致发光改性得到广泛报道。在这项工作中，在单掺杂 Er3+ 和共掺杂 Nd3+ 和 Er3+ 的 YbPO4 反蛋白石中研究了 Er3+ 的上转换发光抑制对近红外发光和协同能量从 Er3+ 到 Yb3+ 的转移的影响。对于 YbPO4:Er3+ 反蛋白石，当光子带隙与 Er3+ 的绿色或红色上转换发光重叠时，在 YbPO4:Er3+ 反蛋白石中，Er3+ 的绿色或红色上转换发光在 980 nm 处被抑制分别激发。观察到 Er3+ 的近红外发光增强具有重要意义，这归因于 YbPO4:Er3+ 反蛋白石中的上转换发光抑制引起的激发能级中的电子重新分布。对于 YbPO4:Nd3+,Er3+ 反蛋白石，在 808 nm 处观察到 Er3+ 的绿色上转换和近红外发光以及 Yb3+ 的近红外发光。Yb3+ 的近红外发光增强是由于绿色上转换发光抑制引起从 Er3+ 到 Yb3+ 的协同能量转移增强。该结果有助于了解稀土离子掺杂材料中上转换与红外发光的关系。在 808 nm 处观察到 Er3+ 的绿色上转换和近红外发光以及 Yb3+ 的近红外发光。Yb3+ 的近红外发光增强是由于绿色上转换发光抑制引起从 Er3+ 到 Yb3+ 的协同能量转移增强。该结果有助于了解稀土离子掺杂材料中上转换与红外发光的关系。在 808 nm 处观察到 Er3+ 的绿色上转换和近红外发光以及 Yb3+ 的近红外发光。Yb3+ 的近红外发光增强是由于绿色上转换发光抑制引起从 Er3+ 到 Yb3+ 的协同能量转移增强。该结果有助于了解稀土离子掺杂材料中上转换与红外发光的关系。
