Journal ArticleDOI
Optical nano-imaging via microsphere compound lenses working in non-contact mode.
Guangxing Wu,Minghui Hong +1 more
TL;DR: A theoretical model involving wave-optics effects is established to guide the design of MCL for different magnifications and imaging configurations, which is more precise compared with common geometric optics theory and will become irreplaceable components to improve the imaging performances of microsphere microscope.
Journal ArticleDOI
Recovering parity-time symmetry in highly dispersive coupled optical waveguides
TL;DR: In this paper, a model system of coupled inorganic semiconductor waveguides with potentially high gain (>1,500 cm-1) and dispersion was studied, and coupled mode theory's parameters were used to quantify smooth transitions between parity-time symmetry phases under imperfect conditions.
Journal ArticleDOI
Synthesis of GaN nanowires on gold-coated substrates by pulsed laser ablation
TL;DR: In this article, the morphological and structural properties of the GaN nanowires were studied using scanning electron microscopy (SEM) and X-ray diffraction (XRD) techniques.
Journal ArticleDOI
Plasmonic enhancement of cyanine dyes for near-infrared light-triggered photodynamic/photothermal therapy and fluorescent imaging
Mindan Lu,Ning Kang,Chuan Chen,Liuqing Yang,Yang Li,Minghui Hong,Xiangang Luo,Lei Ren,Xiumin Wang +8 more
TL;DR: A novel multifunctional nanoagent AuNRs@SiO2-IR795 was developed to realize the integrated photothermal/photodynamic therapy (PTT/PDT) and FLI at a very low dosage of IR795 based on metal-enhanced fluorescence (MEF) effects to highlight the applications of multimodal diagnostics and therapy in tumors based on MEF.
Journal ArticleDOI
Improved optical limiting performance of laser-ablation-generated metal nanoparticles due to silica-microsphere-induced local field enhancement
TL;DR: The optical nonlinear properties of the laser-generated nanoparticle dispersion are studied and it is found that the incident laser beam is locally focused by the microspheres, leading to an increased optical non linearity of the nanoparticles dispersion.
