One of the trends in microelectronics fabrication is to manufacture highly conductive interconnections at a low processing temperature using metallic nanoparticles. In order to obtain excellent electrical conductivity, the surfactants have to be removed and the particles should be well linked. With the assistance of chemical reductants and radiations of flash UV light and near IR, carboxylated-protected...
This paper reports a highly sensitive SERS Diagnosis system by incorporating three dimensional Nano-Mushrooms and Nano-Stars-Array sandwiched on Bacterial Aggregation. Through the action of ACEOF and nano-mushroom/bacteria/nano-stars-array self-aggregation process, the signal can be much enhanced by 5 orders of magnitude in 5 minutes. Detection limit can approach 1 bacterium/ml from the analysis result.
It is well known that the radiation from single nitrogen-vacancy center in a diamond which is placed on a dielectric substrate, propagates into this substrate. This catastrophic problem leads to dramatically reduction of the detected signal level. Here we apply a novel concept of all-dielectic nanoantennas to successfully overcome this problem. We proposed an original all-dielectric nanoantenna which...
This paper reports a novel highly-ordered tripetaloid arrayed structure (TPAS) which performs very well as an active surface-enhanced Raman scattering (SERS) substrate for its notable reproducibility and enormous SERS enhancement factor (EF). The TPAS is easily fabricated by anisotropic etching of a self-assembly silica-nanoparticle bilayer and a following metal deposition. Electromagnetic simulation...
In this paper, composites made by incorporation of ZnO nanoparticles of different concentrations in MEH-PPV was studied. MEH-PPV is a soluble conjugated polymer, one can incorporate oxide nanoparticles into MEH-PPV directly. Optical properties of the hybrid materials and the influence of the nature on the behavior of the composites was investigated and discussed. The polymer was dissolved in tetrahydrofuran...
We design and fabricate a-Si:H solar cells with plasmonic crystal back reflectors demonstrating enhanced absorption of near infrared photons. Rigorous simulations predict plasmonic nanoparticles on ITO can increase absorption in the near infrared. Rigorous simulations also predict plasmonic crystal back reflectors with a pitch of ~750 nm to optimize the enhanced absorption. Such periodic back reflectors...
Surface plasmon resonance is studied for Ag nanoparticles electrochemically deposited on bulk GaP substrates and inside porous GaP templates. The size and density of Ag nanoparticles are controlled by the conditions of electrochemical deposition and thermal processing. The experimental data are analyzed in the frame of the Drude theory taking into account the parameters of the metallic nanoparticles...
Summary form only given. This work presents a systematic study of the surface-enhanced Raman-scattering (SERS) properties of nanoparticle island substrates (NIS) and their application for oligonucleotide target detection. Using NIS that are structurally well characterized by atomic force microscopy (AFM) and UV-VIS extinction spectrum, it demonstrates the correlation of nanostructure of substrates...
