Jian-Heng Chen Graphene-based Micropatterns Using Ultrafast Laser Direct Writing on Ni/C Film
Yu-Hsiang Chen;Jian-Heng Chen;Chun-Yu Lin;Shean-Jen Chen

In this study, to fabricate graphene-based pattern/device by using femtosecond laser direct writing on Ni and C hybrid (Ni@C) film is investigated. The single-step fabrication approach requires no extra film transfer process and provides superior graphene quality compared to chemical vapor deposition.

Bo-Lun Jian Identification of dispersion relation from quasi-whispering gallery modes of an individual CH3NH3PbI3 perovskite microcrystal
Bo-Lun Jian;Zi-Wei Huang;Yan-Ting Liu;Hsu Cheng Hsu

We report on the wavelength dependence of the refractive index in single well-faceted CH3NH3PbI3 perovskite quasi-whispering-gallery-mode (quasi-WGM) microcrystal using micro-photoluminescence technique. The observed cavity modes are well matched to TM polarization quasi-WGMs in long wavelength. We deduced a Sellmeier’s dispersion function for perovskite microcrystals.

Huang Che Hsuan Spectral Model of Multiple-Layer of Hybrid Colloidal Quantum Dots for Light Emitting Diodes
Huang Che Hsuan

A semi-empirical model is developed to model the multiple-layer structure of hybrid colloidal quantum dots in light emitting diodes. The layer-sequence effect of the quantum dots matches with the measured data and the optimal condition is obtained.

Ching-Ting Lee Performance Improvement of Electron Injection Layer in Inverted Polymer White LED with Quantum Dots Emission Layer
Shuo-Wen Yen;Po-Sung Su;Ching-Ting Lee;Hsin-Ying Lee

Various-dimensional CdSe/ZnS quantum dots (QDs) and poly(N-vinylcarbazole) (PVK) polymer material were mixed as the emission layer of inverted white organic light-emitting diodes (WOLEDs). The performances of the WOLEDs with various ZnO thicknesses were investigated. The WOLEDs with a 25-nm-thick ZnO electron injection layer exhibited the luminous efficiency of 2.30 cd/A.

Kuan-Yu Chou Enhanced Near-band-edge Luminescence of Single ZnO Microrod Based Light Emitting Diodes via Coupling with Localized Surface Plasmon of Al nanoparticles
Kuan-Yu Chou;Dai-Jie Lin;Hsu-Cheng Hsu

We demonstrate localized surface plasmon (LSPR) enhanced electroluminescence from n-ZnO microrod/p-GaN light emitting devices decorated with aluminum nanoparticles(Al-NPs). Ultraviolet/violet near-band-edge emission of LED is significantly enhanced more than 5-fold. Reduction in photoluminescence lifetime of ZnO indicates the improved performance of the device stems from LSPR coupling between ZnO and Al-NPs.

Chung-Ping Yu Characteristics of Different Co-Precipitation Methods for Embedded CdTe Quantum Dots
Chung-Ping Yu;Li-Ann Ke;Yu-Ming Huang;Shun-Chieh Hsu;Yin-Han Chen;Chien-Chung Lin;Hao-Chung Kuo

In this paper, three different synthetic methods capped the cadmium telluride quantum dots (CdTe) by sodium chloride crystals. Inorganic NaCl ionic crystal is the protection layer of quantum dots. The aging test is over 900 hours, and the tradition method can maintain the most convert efficiency.
