• World’s first LED lights developed from rice husks
  

  Milling rice to separate the grain from the husks produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot (QD) LED light. Their new m more

• LEDs from bacterial production
  

  In the FET Open project ENABLED, TU Graz protein-designer Gustav Oberdorfer is working together with researchers from Spain and Italy on environmentally friendly and inexpensive light-emitting diodes. The basis for this vision is being laid at the Institute of Biochemistry at Graz University of Tech more

• Electric Cloth: Flexible, wearable supercapacitors based on porous nanocarbon nanocomposites
  

  Evening gowns with interwoven LEDs may look extravagant, but the light sources need a constant power supply from devices that are as well wearable, durable, and lightweight. Chinese scientists have manufactured fibrous electrodes for wearable devices that are flexible and excel by their high energy more

• A novel color-tunable phosphor, Na5Gd9F32:Ln3+ (Ln = Eu, Tb, Dy, Sm, Ho) sub-microcrystals: structure, luminescence and energy transfer properties

  Ln3+-doped fluoride is an economical and highly efficient luminescent material, which plays a crucial role in LEDs, biolabeling, and sensors. Thus, the Na5Gd9F32: Ln3+ sub-microspheres with multicolor tunable emission were successfully synthesized via a simlple water bath method employing Gd(OH)CO3 more

• One-pot synthesize dispersible thermal stable organic downconversion materials under DBU catalyzation for high performance hybrid-LED lamps

  Lighting market has been dominated by light emitting diodes(LEDs), which not only need Ga for for wafer production, but also consume abundant rare-earth elements Y, Ce and Eu. Hybrid-LEDs using organic downconversion materials(ODMs) is a promising candidate technology to save the rare-earth elementa more

• Tunable morphologies, Multicolor Properties and Applications of RE3+ doped NaY(MoO4)2 Nanocrystalls via a facile ligand-assisted reprecipitation Process

  RE3+-doped NaY(MoO4)2 is an efficient material for realizing multicolor emission, which plays an important role in displays, W-LEDs, solar cells and biolabelings. Up to now, researches on the multicolor tuning properties of RE3+-doped NaY(MoO4)2 are mostly through high temperature solid-state reacti more
