Metal-Enhanced Fluorescence from CdTe Nanocrystals: A Single-Molecule Fluorescence Study [PDF]
Journal of the American Chemical Society, 2006 We described, for the first time, the metal-enhanced fluorescence from the CdTe nanocrystals spin coated on silver island films (SIFs). CdTe nanocrystals show approximately 5-fold increase in fluorescence intensity, 3-fold decrease in lifetimes, and reduction in blinking on SIF surfaces that can be observed by ensemble and single-molecule fluorescence ...

Metal-Enhanced Fluorescence in Plasmonic Waveguides [PDF]
, 2017 The field known as plasmonics has seen a tremendous growth in interest from the research community. One of the more popular topics is the surface plasmon waveguide. As an alternative to solid linear nanostructures, a chain of plasmonic nanoparticles can also be used to propagate a traveling wave of surface charges.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...
