中文摘要: |
金纳米粒子具有的特殊光学性质。离子体共振效应是由于其具有的局域表面等。局域表面等离子体共振效应激发态信号。染料分子的使得纳米金可以影响处于其附近的。三线态信号倍数的增强,实现一些研究关注于更高的。目前,分子三线态报道AuNP对染料最大的增强倍数达到10倍。这种方法采用高分子诱导纳米金聚集体形成,等离子体产生了高阶的表面共振,形成更强的电磁场,该电磁场使得处于作用范围的带负电分子的三线态信号有较大倍数的增强。对带正电的染料分子的三线态信号但是这种聚集体还未有报道。因此,在本文中,高分子诱导纳米金我们采用同样的形成。聚集体观察到其对阳离子染料,MB的三线态信号也有增强作用。我们推测纳米金粒子间微环境这是由于仍带负电导致的。 |
外文摘要: |
The gold nanoparticles special optical properties of (AuNPs) are derived from the local surface plasmon resonance effect (LSPR). The LSPR effect dye molecules in its vicinity, could make AuNPs affect the excited state of. According to the current studies, the AuNP could reach 10 folds. Triplet state enhancement factor of the affected by. In this method, the polymer dye molecule molecules were utilized to induce AuNPs forming AuNP aggregates. The AuNP field then forming a stronger electromagnetic. Coupling could generate high order surface plasmon resonance. The electromagnetic field range triplet signal of negatively. Charged molecules in the was enhanced. However, the effect on triplet state signal of positive charged dye molecules by this aggregate has not been reported. Therefore, in this paper, we use AuNP forming the same polymer molecules, to induce mono dispersed AuNP aggregates. By utilizing the AuNP aggregates as antenna, we speculate that due to the microenvironment between MB could also be observed. The gold nanoparticles the enhancement on triplet state signal of cationic dye. It is still negatively charged which make MB adsorbed in the surface of AuNP. |
