Journal ArticleDOI
A novel red phosphor for white light emitting diodes
TL;DR: In this paper, a red phosphor, CaMoO 4 :Eu 3+, has been developed for white light emitting diodes (LEDs), which was prepared by using oxides in air and its luminescent properties have been investigated.
Journal ArticleDOI
Preparation and luminescent properties of (Ca1-x,Srx)S:Eu2+ red-emitting phosphor for white LED
TL;DR: In this article, the (Ca1−x,Srx)S:Eu2+ red-emitting phosphors were prepared by using sulfide and sulfate in CO-reductive atmosphere, respectively, and their luminescent properties have been investigated.
Journal ArticleDOI
A Free‐Standing and Ultralong‐Life Lithium‐Selenium Battery Cathode Enabled by 3D Mesoporous Carbon/Graphene Hierarchical Architecture
TL;DR: In this article, a 3D mesoporous carbon nanoparticles and graphene hierarchical architecture is proposed to store selenium as binder-free cathode material (Se/MCN-RGO) for high energy and long life Li-Se batteries.
Journal ArticleDOI
Free-Standing Nitrogen-doped Graphene Paper as Electrodes for High-Performance Lithium/Dissolved Polysulfide Batteries
Kai Han,Kai Han,Jingmei Shen,Shiqiang Hao,Hongqi Ye,Chris Wolverton,Mayfair C. Kung,Harold H. Kung +7 more
TL;DR: Free-standing N-doped graphene papers, generated by pyrolysis of polydiallyldimethylammonium chloride, were successfully used as binder-free electrodes for the state-of-the-art Li/polysulfide-catholyte batteries.
Journal ArticleDOI
Flexible self-standing graphene–Se@CNT composite film as a binder-free cathode for rechargeable Li–Se batteries
TL;DR: In this paper, a self-standing grapheneeSe@CNT composite film has been synthesized by a facile two-step assembly process, which is directly employed as cathode for rechargeable LieSe batteries without extra binders and conductive additives.
