Localized surface plasmon resonance enhanced photoluminescence of CdSe QDs in PMMA matrix on silver colloids with different shapes

Photoluminescence quenching and enhancement of CdSe/PMMA composite on Au colloids

“…The as-grown Au colloid films were annealed at 550°C for 5 min in a rapidly thermal annealing oven under nitrogen atmosphere. The preparation of CdSe NCs doped polymethyl methacrylate (PMMA) and the growth of CdSe/PMMA composite on Au colloid films were similar to the method described elsewhere [12,13]. The bare glass coated with CdSe/PMMA composite was the reference sample.…”

Thin Layer of Semiconductor Plasmonic Nanocrystals for the Enhancement of NIR Fluorophores

“…Since the demonstration of a 5-fold enhancement in the photoluminescence (PL) of CdSe/ZnS quantum dots (QDs) on gold colloids, many efforts have been made to optimize the plasmon layer deposition, the spatial separation of the particles, and the spectral overlap. , Ag and Au nanoparticles of different shapes, such as nanospheres, , nanoneedles, nanoprisms, or nanocubes, have been studied. The spatial separation between plasmonic and emitting nanoparticles, which is necessary for a balance between PL enhancement and nonradiative quenching, has been often controlled by embedding the nanoparticles into polymers, such as PMMA. ,, …”

Interaction of a novel starch‐capped CdS quantum dots with human serum albumin and bovine serum albumin

“…In addition, to generate suitable surface structure or functionality and thus getting controllable properties, the bare QDs need to be modified with various ligands. There have been several approaches (e.g., bi‐functional covalent linkage, ligand‐exchange, and self‐assembly) to generate QDs with high biocompatibility, water‐solubility, and monodispersity, while their long‐term stability and optical properties be maintained or improved .…”
