Chien-Ming Fan Chiang;Bo-Ren Chang;Ya-Ju Lee;Monima Sarma;Zu-Po Yang;Hai-Ching Su;Hsyi-En Cheng;Ken-Tsung Wong;Yau-Chyr Wang

Here we demonstrated a novel method to improve blue saturation of the sky-blue LECs by engineering its emission spectrum through the plasmonic filters. With the integration of plasmonic filters, the color saturation was improved and the bluest LECs with higher efficiency (among the reported bluest LECs) was obtained.

Neng-Chieh Yu Spectral Study of Silicon Nanostructures at Visible Wavelength
Neng-Chieh Yu;Shu-Cheng Lo;Pei-Kuen Wei;Wan-Shao Tsai

The transmission spectra of low-loss silicon nanoslit array were studied at the visible wavelength. Transmission spectra were measured using an optical microscope and the simulation was based on finite-difference time-domain calculation. Spectral characteristics were discussed based on the slit periods. Both measurement and simulation results are in good agreement.

Bo-Yan Lai Fluorescence Lifetime Modification by Single Gold Nanoparticle Localized Surface Plasmon
Chou Lin Chun;Bo-Yan Lai;Yi-Chun Chen

Interactions between fluorephores and surface plasmon was investigated by a custom-built fluorescence lifetime system. Gold nanoparticle with double-stranded DNA on the surface was utilized to exactly control the distance between fluorephores and the nanoparticle. We calculated surface plasmon-induced changes in the radiative decay rate constant and the quenching rate constant.

Zheng-Ying Lin;Yu-Chueh Hung;Ho-Ting Tung

Gyroid structure has attracted attention owing to its applications in photonic crystals and meta-materials. In this study, we investigate the polarization-dependent characteristics of a hybrid metal/dielectric double gyroid based on finite-difference time domain method. Polarization band gaps and anomalous dispersion are presented based on various hybrid scenarios.

Ching-An LU;Chun-Hung Lin

This study presents a simple process based on nanotransfer printing to fabricate the reduced nanogap dimer-mushroom structure. With this process, we can reveal the electric felid distribution of the structure to boost the sensing.

Shiang-Jen Ren;Chih-Chien Lee;Che-Wei Liu;Ya-Ze Li;Shun-Wei Liu;Sajal Biring;Yi-Nan Lin;Jing-Lin Hsieh;Meng-Zhen Li

We report a fullerene (C60) organic photodetectors with low dark current, by changing the thickness of hole blocking layer. Because of high energy barrier, the dark current could approximately achieve to 0.18 nA cm-2 at -1 V. It means that TAPC could hinder the electrons injection from the ITO

Wei Lun Huang;Tsong Sheng Lay

Self-assembled gold nanoparticles are formed on GaAs substrate by incorporating a heat-absorbing Al2O3 oxide layer. We change the Al2O3 layer thickness to investigate the surface enhance Raman scattering (SERS) effect. We obtain maximum SERS magnification and lowest reflectance at Al2O3 = 11nm. The results are useful in solar cell applications.
