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. |

基本的意思是這樣的。如正式應(yīng)用，需仔細(xì)潤色一下。Enjoy. Thanks. Metal enhanced fluorescence of the fluorescent brightening agent Tinopal-CBX near silver island film 銀島膜附近的熒光增白劑—Tinopal-CBX的金屬增強的熒光 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. 光學(xué)增白劑Tinopal - CBS（4,40-二苯乙烯基聯(lián)苯磺酸鈉鹽）的金屬增強熒光（MEF）／已經(jīng)被／在沉積于玻璃載玻片的銀島膜（SIFS）和吸附于纖維素基濾紙的銀納米顆粒上／使用／穩(wěn)態(tài)和時間分辨熒光測量（技術(shù)）／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. 在銀島膜（SIFS）和吸附于纖維素基濾紙的銀納米顆粒上都觀察到了近4.5倍的熒光強度增強。另外，在銀島膜（SIFS）上也觀察到了增強的光穩(wěn)定性和降低的衰減時間。 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. 這些結(jié)果與MEF的兩種不同的機理相符，其一是熒光團激發(fā)態(tài)能量的耦合和轉(zhuǎn)移到銀島沉積的玻璃膜的表面等離子體激元，其次，電場增強效應(yīng)，這有利于熒光團增強的吸收。我們的研究結(jié)果揭示了顯著的發(fā)光增強和Tinopal CBS的延長光穩(wěn)定性。因此，等離子－TINOPAL結(jié)構(gòu)提供了新的材料，以及在生命科學(xué)領(lǐng)域多方面的的應(yīng)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，我們報道了比不含銀的對照樣品在靠近銀島膜和吸附銀的纖維素紙的Tinopal的金屬增強的吸收、發(fā)射和光穩(wěn)定性。我們的發(fā)現(xiàn)增強了光亮。這些發(fā)現(xiàn)有助于發(fā)展可能用于紡織和造紙上的帶有增強發(fā)光和提高光穩(wěn)定性的光亮劑。 |
