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

Feng Wang,Xiaogang Liu +1 more
TL;DR: This tutorial review focuses on the recent development of various synthetic approaches and possibilities for chemical tuning of upconversion properties, as well as giving an overview of biological applications of these luminescent nanocrystals.
Journal ArticleDOI
Tuning upconversion through energy migration in core–shell nanoparticles
Feng Wang,Renren Deng,Juan Wang,Qingxiao Wang,Yu Han,Haomiao Zhu,Xueyuan Chen,Xiaogang Liu,Xiaogang Liu +8 more
TL;DR: By rational design of a core-shell structure with a set of lanthanide ions incorporated into separated layers at precisely defined concentrations, efficient upconversion emission can be realized through gadolinium sublattice-mediated energy migration for a wide range of Lanthanide activators without long-lived intermediary energy states.
Journal ArticleDOI
Upconversion multicolor fine-tuning: visible to near-infrared emission from lanthanide-doped NaYF4 nanoparticles.
Feng Wang,Xiaogang Liu +1 more
TL;DR: A general approach to fine-tuning the upconversion emission colors, based upon a single host source of NaYF4 nanoparticles doped with Yb3+, Tm3+, and Er3+, is presented.
Journal ArticleDOI
Upconversion nanoparticles in biological labeling, imaging, and therapy
TL;DR: Recent developments in optical biolabeling and bio-imaging involving upconversion nanoparticles are reviewed, simultaneously bringing to the forefront the desirable characteristics, strengths and weaknesses of these luminescent nanomaterials.
