Multicolor directional surface plasmon-coupled chemiluminescence

Article Abstract:

The concept of surface plasmon-coupled luminescence is extended to include chemiluminescencing species and the observation of surface plasmon-coupled chemiluminescence (SPCC), where the luminescence from chemically induced electronic excited states couples to surface plasmons in a thin continuous metal film is reported. The SPCC is highly directional and predominantly p-polarized, strongly suggesting that the emission is from surface plasmons instead of the luminophores themselves.

Surface-plasmon-coupled emission of quantum dots

Article Abstract:

Surface plasmon-coupled emission (SPCE) of semiconductor quantum dots (QDs) was studied. Excited QDs induced surface plasmons in a thin silver layer when these QDs were stabilized using lysine cross-linked mercaptoundecanoic acid and spin-coated from 0.75 percent PVA solution on a glass slide covered with 50nm of silver and a 5-nm protective SiO2 layer.

Combined quantum mechanical/molecular mechanical study on the pentacoordinated ferric and ferrous cytochrome P450(sub cam) complexes

Article Abstract:

The pentacoordinated ferric and ferrous cytochrome P450(sub cam) complexes is investigated. The results reveal that the amount to stabilization by the protein environment is largest for the intermediate-spin states, followed by the high-spin states of the complexes.
