Surfactant-Induced Modulation of Nanometal Surface Energy Transfer from Silicon Quantum Dots to Silver Nanoparticles

Abstract: In the present study, we have demonstrated the excitation energy transfer (EET) from silicon quantum dots (Si QDs) to silver nanoparticles (Ag NPs) and its modulation in the presence of cetyltrimethylammonium bromide (CTAB) surfactant by means of steady-state and time-resolved photoluminescence (PL) spectroscopy. Significant spectral overlap between the emission spectrum of Si QDs and localized surface plasmon resonance of Ag NPs results in a substantial amount of PL quenching of Si QDs. In addition, the PL li… Show more

“…Therefore, the radius d 0 can be calculated by where Φ ET is the energy-transfer efficiency, d is the separation distance between Au NPs and proximal ABEI, n is the power that owns a value of 6 for FRET (r 0 = R 0 ) or 4 for NSET (r 0 = d 0 ), respectively. 13 When Φ ET was 56%, the estimated separation distances between Au NPs and proximal ABEI based on FRET and NSET mechanisms were calculated to be 13.29 and 3.33 nm, respectively. However, it should be highlighted that in a qualified ECL quenching system based on FRET theory, the Forster distance R 0 value should be in the range of 2−6 nm and the distance should be no longer than 10 nm.…”

“…17 Due to the long steric distance between the primary amino group and benzene ring, ABEI exhibits favorable reducibility and has been used for in situ preparation of Au NPs in ECL sensing systems. 17,18 For improving the biocompatibility of biosensors, some nanosized biomaterials such as DNA nanoscaffolds 13,19 and protein nanocages 20 have been explored as ECL nanocarriers. Ferritin is a ubiquitous iron-storage protein which encapsulates a ferric nanocore within a nanocage composed of 24 subunits.…”

“…263 There has been continued use of plasmonic substrates for enhancing the photophysical properties of luminescent particles. 264,265 To this list, quantum dots have been extensively studied, not only to enhance their luminescence but to additionally improve quantum dot photostability. 265 In addition, a recent report has appeared on the use of plasmonic substrates to enhance the intrinsic emission of carbon nanodots, 266 small amorphous carbon nanoparticles formed from burning hydrocarbons.…”
