Management of singlet and triplet excitons for efficient white organic light-emitting devices
Yiru Sun,Noel C. Giebink,Hiroshi Kanno,Biwu Ma,Mark E. Thompson,Stephen R. Forrest,Stephen R. Forrest +6 more
TL;DR: This device challenges incandescent sources by exhibiting total external quantum and power efficiencies that peak at 18.7 ± 0.6 lm W-1, respectively, and two distinct modes of energy transfer within this device serve to channel nearly all of the triplet energy to the phosphorescent dopants, retaining the singlet energy exclusively on the blue fluorescent dopant.
Journal ArticleDOI
User-interactive electronic skin for instantaneous pressure visualization
Chuan Wang,David J. Hwang,David J. Hwang,Zhibin Yu,Zhibin Yu,Kuniharu Takei,Kuniharu Takei,Junwoo Park,Teresa Chen,Biwu Ma,Ali Javey,Ali Javey +11 more
TL;DR: This work reports the first user-interactive e-skin that not only spatially maps the applied pressure but also provides an instantaneous visual response through a built-in active-matrix organic light-emitting diode display with red, green and blue pixels.
Journal ArticleDOI
Flexible, highly efficient all-polymer solar cells
Taesu Kim,Jae-Han Kim,Tae Eui Kang,Changyeon Lee,Hyunbum Kang,Minkwan Shin,Cheng Wang,Biwu Ma,Unyong Jeong,Taek-Soo Kim,Bumjoon J. Kim +10 more
TL;DR: The proposed all-polymer solar cells have even better performance than the control polymer-fullerene devices with phenyl-C61-butyric acid methyl ester as the electron acceptor and exhibit dramatically enhanced strength and flexibility compared with polymer/PCBM devices.
Journal ArticleDOI
One-dimensional organic lead halide perovskites with efficient bluish white-light emission.
Zhao Yuan,Chenkun Zhou,Yu Tian,Yu Shu,Joshua Messier,Jamie C. Wang,Lambertus J. van de Burgt,Konstantinos Kountouriotis,Yan Xin,Ethan D. Holt,Kirk S. Schanze,Ronald A. Clark,Theo Siegrist,Theo Siegrist,Biwu Ma,Biwu Ma +15 more
TL;DR: This work verifies once again that one-dimensional systems are favourable for exciton self-trapping to produce highly efficient below-gap broadband luminescence, and opens up a new route towards superior light emitters based on bulk quantum materials.
Journal ArticleDOI
Low-Dimensional Organometal Halide Perovskites
TL;DR: In this paper, a perspective on the most exciting developments in the low-dimensional organometal halide perovskites is presented, which are significantly different from those of 3D and 2D structures.
