A Highly Efficient Host/Dopant Combination for Blue Organic Electrophosphorescence DevicesAdvanced Functional Materials - Tập 18 Số 3 - Trang 485-491 - 2008
Jin‐Ju Lin, Wei‐Shieng Liao, Hsiang‐Jung Huang, Fang‐Iy Wu, Chien‐Hong Cheng
AbstractWe have synthesized a new blue‐emitting iridium complex, FIrpytz (iridium(III) bis(4,6‐difluorophenylpyridinato)‐4‐(pyridin‐2‐yl)‐1,2,3‐triazolate), and two new bis(triphenylsilyl) derivatives, BSB (4,4'‐bis‐triphenylsilanyl‐biphenyl) and BST (4,4″‐bis(triphenylsilanyl)‐(1,1′,4′,1″)‐terphenyl) as hosts for blue phosphorescence devices. The photoluminescence...... hiện toàn bộ
One‐Step Ionic‐Liquid‐Assisted Electrochemical Synthesis of Ionic‐Liquid‐Functionalized Graphene Sheets Directly from GraphiteAdvanced Functional Materials - Tập 18 Số 10 - Trang 1518-1525 - 2008
Na Liu, Fang Luo, Haoxi Wu, Yinghui Liu, Chao Zhang, Ji Chen
AbstractGraphite, inexpensive and available in large quantities, unfortunately does not readily exfoliate to yield individual graphene sheets. Here a mild, one‐step electrochemical approach for the preparation of ionic‐liquid‐functionalized graphite sheets with the assistance of an ionic liquid and water is presented. These ionic‐liquid‐treated graphite sheets can ...... hiện toàn bộ
Rapid Degradation of Azo Dye by Fe‐Based Metallic Glass PowderAdvanced Functional Materials - Tập 22 Số 12 - Trang 2567-2570 - 2012
J.Q. Wang, Yan Hui Liu, Mingwei Chen, Guoqiang Xie, D. V. Louzguine, Akihisa Inoue, John H. Perepezko
AbstractThe outstanding efficiency of Fe‐based metallic glass powders in degrading organic water contaminants is reported. While the glassy alloy contains 24% chemically inactive metalloid elements, the powders are capable to completely decompose the C32H20N6Na4O14... hiện toàn bộ
Revisiting the Structure of Graphene Oxide for Preparing New‐Style Graphene‐Based Ultraviolet AbsorbersAdvanced Functional Materials - Tập 22 Số 12 - Trang 2542-2549 - 2012
Wenhui He, Lehui Lu
AbstractDespite sustained effort over the years, the exploration of an effective strategy toward understanding the structure and properties of graphene oxide (GO) is still highly desirable. Herein, a facile route to revisit the structure of GO is demonstrated by elucidating its chemical‐conversion process solely in the presence of ammonia. Such a strategy can contr...... hiện toàn bộ
Characteristics of Solution‐Processed Small‐Molecule Organic Films and Light‐Emitting Diodes Compared with their Vacuum‐Deposited CounterpartsAdvanced Functional Materials - Tập 19 Số 10 - Trang 1625-1630 - 2009
Tae‐Woo Lee, Taeyong Noh, Hee-Won Shin, Ohyun Kwon, Jongjin Park, Byoung Ki Choi, Myeong Suk Kim, Dong Woo Shin, Yong Rok Kim
AbstractAlthough significant progress has been made in the development of vacuum‐deposited small‐molecule organic light‐emitting diodes (OLEDs), one of the most desired research goals is still to produce flexible displays by low‐cost solution processing. The development of solution‐processed OLEDs based on small molecules could potentially be a good approach but no...... hiện toàn bộ
Organometal Halide Perovskite Quantum Dot Light‐Emitting DiodesAdvanced Functional Materials - Tập 26 Số 26 - Trang 4797-4802 - 2016
Wei Deng, Xiuzhen Xu, Xiujuan Zhang, Yedong Zhang, Xiangcheng Jin, Liang Wang, Shuit‐Tong Lee, Jiansheng Jie
Organometal halide perovskites quantum dots (OHP‐QDs) with bright, color‐tunable, and narrow‐band photoluminescence have significant advantages in display, lighting, and laser applications. Due to sparse concentrations and difficulties in the enrichment of OHP‐QDs, production of large‐area uniform films of OHP‐QDs is a challenging task, which largely impedes their use in electroluminescenc...... hiện toàn bộ
Improved Performance and Stability of All‐Inorganic Perovskite Light‐Emitting Diodes by Antisolvent Vapor TreatmentAdvanced Functional Materials - Tập 27 Số 28 - 2017
Wu Chen, Yatao Zou, Tian Wu, Muyang Ban, Vincenzo Pecunia, Yujie Han, Qipeng Liu, Tao Song, Steffen Duhm, Baoquan Sun
All‐inorganic perovskite light‐emitting diodes (LEDs) reveal efficient luminescence with high color purity, but their modest brightness and poor stability are still critical drawbacks. Here, the luminescent efficiency and the stability of perovskite LEDs (PeLEDs) are boosted by antisolvent vapor treatment of CsPbBr3 embedded in a dielectric polymer matrix of polyethyle...... hiện toàn bộ
Solution‐Processed Extremely Efficient Multicolor Perovskite Light‐Emitting Diodes Utilizing Doped Electron Transport LayerAdvanced Functional Materials - Tập 27 Số 21 - 2017

A specially designed n‐type semiconductor consisting of Ca‐doped ZnO (CZO) nanoparticles is used as the electron transport layer (ETL) in high‐performance multicolor perovskite light‐emitting diodes (PeLEDs) fabricated using an all‐solution process. The band structure of the ZnO is tailored via Ca doping to create a cascade of conduction energy levels from the cathode to the perovskite. Th...... hiện toàn bộ
