Journal ArticleDOI
Light emitting diode irradiation can control the morphology and optical properties of silver nanoparticles.
TL;DR: A facile method for the preparation of silver nanoparticles (AgNPs) of various sizes and morphologies, including dodecahedra, nanorods, and nanoplates, has been discovered by choosing the desired optical properties and irradiating spherical AgNP seeds with a selected light emitting diode.
Journal ArticleDOI
Optimal Size of Silver Nanoparticles for Surface-Enhanced Raman Spectroscopy
TL;DR: The optimal size of spherical silver nanoparticles for off-resonance surface-enhanced Raman scattering (SERS) was found to be ∼50 nm based on the equivalent Ag content in AgNP colloids as discussed by the authors.
Journal ArticleDOI
Dual nature of the excited state in organic–inorganic lead halide perovskites
TL;DR: In this article, the authors investigated the nature of perovskite absorption features and optical properties and proposed a band structure composed of two distinct transitions that is consistent with the various spectral features and kinetic behavior of the CH3NH3PbI3 excited state.
Journal ArticleDOI
Size-Dependent Excited State Behavior of Glutathione-Capped Gold Clusters and Their Light-Harvesting Capacity
TL;DR: Gold clusters, Au18GSH14, were found to have the highest potential as a photosensitizer on the basis of the quantum yield of electron transfer and good visible light absorption properties.
Journal ArticleDOI

TL;DR: While keratinocytes and fibroblasts were not affected by AgNP@collagen, it was bactericidal against Bacillus megaterium and E. coli but only bacteriostatic against S. epidermidis, and was stable over a remarkable range of NaCl, phosphate, and 2-(N-morpholino)ethanesulfonic acid concentrations and for over one month at 4 °C.
