| 1 | A full multigrid method for nonlinear eigenvalue problems显示文摘We introduce a type of full multigrid method for the nonlinear eigenvalue problem. The main idea is to transform the solution of the nonlinear eigenvalue problem into a series of solutions of the corresponding linear boundary value problems on the sequence of finite element spaces and nonlinear eigenvalue problems on the coarsest finite element space. The linearized boundary value problems are solved by some multigrid iterations.Besides the multigrid iteration, all other efficient iteration methods for solving boundary value problems can serve as the linear problem solver. We prove that the computational work of this new scheme is truly optimal,the same as solving the linear corresponding boundary value problem. In this case, this type of iteration scheme certainly improves the overfull efficiency of solving nonlinear eigenvalue problems. Some numerical experiments are presented to validate the efficiency of the new method. | JIA ShangHui XIE HeHu XIE ManTing XU Fei | 2016 | Science China Mathematics2016，59，10： | 7 |
| 2 | Aggregation-enhanced emission and efficient electroluminescence of conjugated polymers containing tetraphenylethene units显示文摘Tetraphenylethene (TPE) is a popular luminogen characterized by aggregation-induced emission and has been widely used to construct solid-state emissive materials. In this work, two thermally stable polymers (P1 and P2) consisting of TPE conjugated to the 2,7-positions of fluorene and carbazole, respectively, are synthesized and characterized. Both polymers are weakly fluorescent in solutions but show greatly enhanced emission as the aggregate formation, presenting an aggregation-enhanced emission feature. Two kinds of polymer light-emitting diodes are fabricated utilizing P1 and P2 as emitters (EML) (device I: ITO/PEDOT:PSS (45 nm)/PVK:EML (1:1 wt%, 55 nm)/TPBI (38 nm)/Ca:Ag; device II: ITO/PEDOT:PSS (45 nm)/ PVK:OXD-7:EML (3:1:3 wt%, 55 nm)/TPBI (38 nm)/Ca:Ag). The device II of P2 shows the best performances, affording a maximum luminance of 6500 cd/m 2 and a high peak efficiency of 2.11 cd/A. | HE BaiRong YE ShangHui GUO YanJu CHEN Bin XU XiaoFei QIU HuaYu ZHAO ZuJin | 2013 | Science China Chemistry2013，56，9： | 2 |
| 3 | A posteriori error estimator for eigenvalue problems by mixed finite element method显示文摘In this paper,a residual type of a posteriori error estimator for the general second order elliptic eigenpair approximation by the mixed finite element method is derived and analyzed,based on a type of superconvergence result of the eigenfunction approximation.Its efficiency and reliability are proved by both theoretical analysis and numerical experiments. | JIA ShangHui CHEN HongTao XIE HeHu | 2013 | Science China Mathematics2013，56，5： | 2 |
| 4 | Blue AIEgens bearing triphenylethylene peripheral:adjustable intramolecular conjugation and good device performance显示文摘The new approaches to construct deep blue aggregation-induced emission(AIE) materials have been explored, which control the conjugation by two different strategies, to make a great step for the commercialization of organic light-emitting diodes. In order to shorten the intramolecular conjugation length, triphenylethylene(t PE)was utilized to construct blue AIEgens as peripheral groups,instead of tetraphenylethylene(TPE), the famous AIE star molecule, to yield three blue AIEgens of 3,4-Bt PE-PI, 4,4-Bt PE-PI and 4,4-Bt PE-PPI. Nondoped electroluminescence devices are fabricated by using these three AIEgens as the emitting material layer, the best performance of 3.8 cd/A as the maximum current efficiency achieved at the commission internationale de l'Eclairage coordinates of(0.17, 0.18). | Can Wang Le Li Xuejun Zhan Zhijun Ruan Yujun Xie Quanyuan Hu Shanghui Ye Qianqian Li Zhen Li | 2016 | Science Bulletin2016，61，22： | 2 |
