| 1 | Electron transition manipulation under graphene-mediated plasmonic engineering nanostructure显示文摘Monolayer graphene has attracted enormous attention owing to its unique electronic and optical properties.However,achieving an effective approach without applying electrical bias for manipulating the charge transfer based on graphene is elusive to date.Herein,we realized the manipulation of excitons’transition from emitter to the graphene surface with plasmonic engineering nanostructures and firstly obtained large enhancements for photon emission on the graphene surface.The localized plasmons generated from the plasmonic nanostructures of shell-isolated nanoparticle coupling to ultra-flat Au substrate would dictate a consistent junction geometry while enhancing the optical field and dominating the electron transition pathways,which may cause obvious perturbations for molecular radiation behaviors.Additionally,the three-dimensional finite-difference time-domain and time-dependent density functional theory were also carried out to simulate the distributions of electromagnetic field and energy levels of hybrid nanostructure respectively and the results agreed well with the experimental data.Therefore,this work paves a novel approach for tunning graphene charge/energy transfer processes,which may hold great potential for applications in photonic devices based on graphene. | Huaizhou Jin Jing-Yu Wang Xia-Guang Zhang Weiyi Lin Weiwei Cai Yue-Jiao Zhang Zhi-Lin Yang Fan-Li Zhang Jian-Feng Li | 2023 | Nano Research2023，16，4： | 0 |
| 2 | The dielectric and ferroelectric properties of (Ba_(0.5)Sr_(0.5))TiO_(3)-doped (Bi_(0.5)Na_(0.5))TiO_(3) lead-free ceramics显示文摘This work prepares(Ba_(05)Sr_(0.5))TiO_(3)(BST)-doped(Bi_(1/2)Na_(1/2))TiO_(3)(NBT)lead free ceramics through conventional solid reaction method and analyzes the doping effect of BST on phases,microstructure,dielectric and ferroelectric properties.The phase and structure of the NBT-BST ceramics were investigated through X-ray diffractometer(XRD)and Raman.The XRD results showed that BST has diffused into the NBT lattices to form a stable solid solution;while,Raman spectrum showed the bands at low frequency are different with that of pure NBT and divided into two ranges around 247 cm^(-1) and 303 cm^(-1).Relative dense and homogeneous ceramic microstructures could be achieved,with the observation of a slight decrease in average grain size with the increase of BST doping content.The dielectric and ferroelectric properties were also investigated.The dielectric constant increases gradually with increasing the temperature to T_(m),and then decrease.The temperature dependence property showed diffused phase transition near T_(m).The polarization-electric field(P-E)hysteresis loops of BST-doped NBT ceramics showed typical ferroelectric or relaxor nature.Both the E_(c) and P_(r) increased first,then decreased with respect to the increase of the BST content. | Guoliang Xue Qiankun Wu Gang Li Huaizhou Lin Gang Liu Yi Chen Xiaokui Liu Yan Yan | 2017 | Journal of Advanced Dielectrics2017，7，4： | 0 |
| 3 | Manipulating the light-matter interactions in plasmonic nanocavities at 1 nm spatial resolution显示文摘The light-matter interaction between plasmonic nanocavity and exciton at the sub-diffraction limit is a central research field in nanophotonics.Here,we demonstrated the vertical distribution of the light-matter interactions at~1 nm spatial resolution by coupling A excitons of MoS2 and gap-mode plasmonic nanocavities.Moreover,we observed the significant photoluminescence(PL)enhancement factor reaching up to 2800 times,which is attributed to the Purcell effect and large local density of states in gap-mode plasmonic nanocavities.Meanwhile,the theoretical calculations are well reproduced and support the experimental results. | BAO-YING WEN JING-YU WANG TAI-LONG SHEN ZHEN-WEI ZHU PENG-CHENG GUAN JIA-SHENG LIN WEI PENG WEI-WEI CAI HUAIZHOU JIN QING-CHI XU ZHI-LIN YANG ZHONG-QUN TIAN JIAN-FENG LI | 2022 | Light(Science & Applications)2022，11，9： | 0 |
