Metal enhanced fluorescence of the fluorescent brightening agent Tinopal-CBX near silver island film Metal-enhanced fluorescence (MEF) studies of the optical brightener Tinopal-CBS (4,40- distyrylbiphenyl sulfonic sodium salt) have been undertaken using steady-state and time resolved fluorescence measurements on silver island films (SiFs) deposited on glass slides and silver nano-particles adsorbed onto cellulose based filter paper. Nearly a 4.5 fold enhancement in fluorescence intensity is observed from both SiFs and nano-particle deposited cellulose filter paper. In addition an enhanced photostability and decrease in decay time is also observed on SiFs. These results are consistent with two distinct mechanisms of MEF, firstly coupling and transferring of the excited states energies of fluorophores to surface plasmons in the silver island deposited glass films, and secondly, an electric field enhancement effect, which facilitates enhanced absorption of the fluorophores. Our findings reveal significant benefits of enhanced luminescence and prolonged photostability of Tinopal CBS. As such, Plasmon-tinopal constructs offer new material opportunities as well as multifarious applications in the life sciences. In this paper, we have reported metal-enhanced absorption, emission and photostability of Tinopal in close proximity to SiFs and silver adsorbed cellulose paper as compared to an identical control sample containing no silver. Our findings enhanced optical brighteners These findings are helpful in the development of enhanced luminescence and prolonged photostability of optical brightener for potential applications on textiles and papers. |

基本的意思是这样的。如正式应用，需仔细润色一下。Enjoy. Thanks. Metal enhanced fluorescence of the fluorescent brightening agent Tinopal-CBX near silver island film 银岛膜附近的荧光增白剂—Tinopal-CBX的金属增强的荧光 Metal-enhanced fluorescence (MEF) studies of the optical brightener Tinopal-CBS (4,40- distyrylbiphenyl sulfonic sodium salt) have been undertaken using steady-state and time resolved fluorescence measurements on silver island films (SiFs) deposited on glass slides and silver nano-particles adsorbed onto cellulose based filter paper. 光学增白剂Tinopal - CBS（4,40-二苯乙烯基联苯磺酸钠盐）的金属增强荧光（MEF）／已经被／在沉积于玻璃载玻片的银岛膜（SIFS）和吸附于纤维素基滤纸的银纳米颗粒上／使用／稳态和时间分辨荧光测量（技术）／研究了／。 Nearly a 4.5 fold enhancement in fluorescence intensity is observed from both SiFs and nano-particle deposited cellulose filter paper. In addition an enhanced photostability and decrease in decay time is also observed on SiFs. 在银岛膜（SIFS）和吸附于纤维素基滤纸的银纳米颗粒上都观察到了近4.5倍的荧光强度增强。另外，在银岛膜（SIFS）上也观察到了增强的光稳定性和降低的衰减时间。 These results are consistent with two distinct mechanisms of MEF, firstly coupling and transferring of the excited states energies of fluorophores to surface plasmons in the silver island deposited glass films, and secondly, an electric field enhancement effect, which facilitates enhanced absorption of the fluorophores. Our findings reveal significant benefits of enhanced luminescence and prolonged photostability of Tinopal CBS. As such, Plasmon-tinopal constructs offer new material opportunities as well as multifarious applications in the life sciences. 这些结果与MEF的两种不同的机理相符，其一是荧光团激发态能量的耦合和转移到银岛沉积的玻璃膜的表面等离子体激元，其次，电场增强效应，这有利于荧光团增强的吸收。我们的研究结果揭示了显著的发光增强和Tinopal CBS的延长光稳定性。因此，等离子－TINOPAL结构提供了新的材料，以及在生命科学领域多方面的的应用。 In this paper, we have reported metal-enhanced absorption, emission and photostability of Tinopal in close proximity to SiFs and silver adsorbed cellulose paper as compared to an identical control sample containing no silver. Our findings enhanced optical brighteners. These findings are helpful in the development of enhanced luminescence and prolonged photostability of optical brightener for potential applications on textiles and papers. 在本文中，我们报道了比不含银的对照样品在靠近银岛膜和吸附银的纤维素纸的Tinopal的金属增强的吸收、发射和光稳定性。我们的发现增强了光亮。这些发现有助于发展可能用于纺织和造纸上的带有增强发光和提高光稳定性的光亮剂。 |
