Eu/Tb co-doped films with low concentration gold nanorods have been prepared using the solution process. The luminescence spectra investigations indicate that the introduction of nanorods can effectively enhance the energy transfer from Tb to Eu under excitation of 292 nm, because of the plasmonic coupling with excited Tb complex. Under excitation of 360 nm, the emission at 612 nm is enhanced, the enhancement factor increases and then decreases as the molar ratio of Tb and Eu increases. The luminescence enhancement is attributed to the metal enhanced luminescence resulting from plasmonic coupling with excited Eu complex. The dual effects of LSPR on energy transfer and emission enhancement are both observed. More details on the luminescence of Eu/Tb co-doped films with nanorods are demonstrated, which gain a deeper understanding of the interactions luminescent-particle and luminescent-luminescent.

低浓度金纳米棒对Eu / Tb共掺杂薄膜中能量转移和发光增强的双重耦合效应。

使用溶液法制备了具有低浓度金纳米棒的Eu / Tb共掺杂薄膜。发光光谱研究表明，纳米棒的引入可以有效地增强在292 nm激发下从Tb到Eu的能量转移，这是因为与激发的Tb络合物发生了等离子体耦合。在360 nm激发下，612 nm处的发射增强，增强因子随Tb和Eu摩尔比的增加而增加，然后降低。发光增强归因于与激发的Eu络合物的等离子体耦合导致的金属增强的发光。均观察到LSPR对能量转移和排放增强的双重作用。展示了有关Eu / Tb纳米棒共掺杂薄膜发光的更多细节，
