Photochemical Decoration of Ag Nanoparticles on Flower-like ZnO for Surface Enhanced Raman Scattering
Nazar Riswana Barveen;Tzyy-Jiann Wang

Strong Raman signal enhancement by the synergistic effect of Ag nanoparticles decorated on flower-like ZnO is presented. The semiconductor/noble-metal nanostructure is synthesized by the photochemical process. The produced SERS substrate achieves high performance, including the enhancement factor as high as 1.40×10^8 and the ultra-low limit of detection of 10^-10 M.

Lasing from Plasmonic Surface Lattice Resonances in Silver Particle Arrays Coupled with Perovskite Thin Films
Chiao-Yun Chang;Chih-Wei Yin;Tien-Chang Lu

We investigate a plasmon-exciton-polaritons (PEPs) lasing by fabricating silver particle arrays covered with perovskite thin film. Plasmonic surface lattice resonances (SLRs) are generated by the silver particle array and couple with the upper perovskite film to achieve ultra-low threshold lasing.

Photoinduced Work-Function Tuning via Strong Coupling of MoS2 Monolayers in 1D Plasmonic Nanogrooves Hybrid Systems
Min-Wen Yu;Satoshi Ishii;Shisheng Li;Ji-Ren Ku;Jhen-Hong Yang;Kuan-Lin Su;Takaaki Taniguchi;Tadaaki Nagao;Kuo-Ping Chen

The MoS2 monolayers loaded on 1D plasmonic nanogrooves exhibit the largest Rabi splitting energy of ~65 meV at room temperature. Additionally, the work-function modulations of the samples due to the strong coupling of the MoS2 excitons and plasmons are quantitatively revealed by the Kelvin probe force microscope under photoexcitation.

Enhanced Light Extraction Efficiency of Two-Dimensional Tungsten Diselenide (WSe2) Atomic Layer with Scattered Microdisk Cavity
Tzu-Wei Huang

In this study, we integrated the monolayer tungsten diselenide (WSe2) with the microdisk cavities, and investigated the different types microdisk cavities to achieve the higher light extraction efficiency for 2-D TMDC emission.

Full laser processed Au NPs/IZO photodetector for colorimetric salivary urea sensing
Ching-Fu Lin;Dominique Berling;Hsiao-Wen Zan;Olivier Soppera

A novel full laser processed Au NPs/indium-zinc-oxide photodetector is successfully demonstrated. The coupling of Au NPs not only improves the absorbing range, but assists indium-zinc-oxide layer curing by thermoplasmonic effect. The photodetector performs wide range detection from 410-780 nm, and be further used for identifying colorimetric urea concentration signals.
