Journal ArticleDOI
Simultaneous phase and size control of upconversion nanocrystals through lanthanide doping
Feng Wang,Yu Han,C. S. Lim,Yunhao Lu,Juan Wang,Jun Xu,Hongyu Chen,Chun Zhang,Minghui Hong,Minghui Hong,Xiaogang Liu +10 more
TL;DR: The results suggest that the doping-induced structural and size transition, demonstrated here in NaYF4 upconversion nanocrystals, could be extended to other lanthanide-doped nanocrystal systems for applications ranging from luminescent biological labels to volumetric three-dimensional displays.
Journal ArticleDOI
Temporal full-colour tuning through non-steady-state upconversion
TL;DR: This work demonstrates a convenient, versatile approach to dynamically fine-tuning emission in the full colour range from a new class of core-shell upconversion nanocrystals by adjusting the pulse width of infrared laser beams and suggests that the unprecedented colour tunability from these nanocry crystals is governed by a non-steady-state upconverting process.
Journal ArticleDOI
Sub-diffractional volume-confined polaritons in the natural hyperbolic material hexagonal boron nitride
Joshua D. Caldwell,Andrey V. Kretinin,Yiguo Chen,Vincenzo Giannini,Michael M. Fogler,Yan Francescato,Chase T. Ellis,Joseph G. Tischler,Colin R. Woods,Alexander J. Giles,Minghui Hong,Kenji Watanabe,Takashi Taniguchi,Stefan A. Maier,Kostya S. Novoselov +14 more
TL;DR: Three-dimensionally confined 'hyperbolic polaritons' in boron nitride nanocones that support four series (up to the seventh order) modes in two spectral bands are reported on.
Journal ArticleDOI
Optical virtual imaging at 50 nm lateral resolution with a white-light nanoscope
Zengbo Wang,Wei Guo,Lin Li,Boris Luk'yanchuk,Ashfaq Khan,Zhu Liu,Zaichun Chen,Zaichun Chen,Minghui Hong,Minghui Hong +9 more
TL;DR: A new 50-nm-resolution nanoscope that uses optically transparent microspheres as far-field superlenses (FSL) to overcome the white-light diffraction limit is reported, which may provide new opportunities to image viruses and biomolecules in real time.
Journal ArticleDOI
Catenary optics for achromatic generation of perfect optical angular momentum
Mingbo Pu,Xiong Li,Xiaoliang Ma,Yanqin Wang,Zeyu Zhao,Changtao Wang,Chenggang Hu,Ping Gao,Cheng Huang,Haoran Ren,Xiangping Li,Fei Qin,Jing Yang,Min Gu,Minghui Hong,Xiangang Luo +15 more
TL;DR: It is shown that the optical catenary can serve as a unique building block of metasurfaces to produce continuous and linear phase shift covering [0, 2π], a mission that is extremely difficult if not impossible for state-of-the-art technology.
