Metal-enhanced fluorescence of mixed coumarin dyes by silver and gold nanoparticles: Towards plasmonic thin-film luminescent solar concentrator

Silver and gold nanoparticles from tannic acid: synthesis, characterization and evaluation of antileishmanial and cytotoxic activities

“…AuNPs-Cit and AgNPs-Cit exhibited SPR bands at 519 and 442 nm, respectively, which are values consistent with those previously reported (Fig. S2) (El-Bashir et al 2013, Silva et al 2013. Furthermore, both TA-coated nanoparticles have broader bands than citrate-coated ones, indicating an increase in the size or aggregation of nanoparticles (Melo et al 2012), later proved by TEM measurements.…”

Metal-enhanced fluorescence effect of Ag and Au nanoparticles modified with rhodamine derivative in detecting Hg2+

“…In recent years, there has been an explosion in the use of metallic nanostructures to favorably modify the spectral properties of fluorophores and to alleviate photophysical constraints of these fluorophores [13,14]. The ability of noble-metal nanoparticles to amplify fluorescence signals and increase a fluorophore's quantum yield has caused important changes to fluorescence spectroscopy as well as to its applications [15]. Aside from reducing the fluorescence lifetime of fluorophores, the metal nanoparticles are capable of enhancing the local electromagnetic radiation field near the emitter and increasing the possibility of its excitation [16,17].…”

Thin-Film LSCs Based on PMMA Nanohybrid Coatings: Device Optimization and Outdoor Performance

“…This paper deals with the problems which hampered the development of LSCs such as the stability of luminescent organic dyes and the matrix configuration [9]. The first problem can be solved by using fluorescent dyes specialized in engineering plastics such as MACROLEX fluorescent dyes (Bayer, Germany); these dyes have been reported to have a promising thermal and photostability in LSC applications [10]. The second problem can be faced by thin-film LSC configuration (TLSC) shown in Figure 2 which was proposed to reduce the reabsorption of fluorescent photons and scattering losses.…”
