• On the way to printable organic light emitting diodes
  

  Organic light-emitting diodes (OLEDs) are used today in many electronic devices for display applications, ranging from smartphones to televisions. Scientists at the Max Planck Institute for Polymer Research (MPI-P) have now succeeded in developing a new design for these LEDs. They have been able to more

• Radical approach for brighter LEDs
  

  Scientists have discovered that semiconducting molecules with unpaired electrons, termed 'radicals' can be used to fabricate very efficient organic-light-emitting diodes (OLEDs), exploiting their quantum mechanical 'spin' property to overcome efficiency limitations for traditional, non-radical mater more

• New efficiency record set for perovskite LEDs
  

  Researchers have set a new efficiency record for LEDs based on perovskite semiconductors, rivalling that of the best organic LEDs (OLEDs). Compared to OLEDs, which are widely used in high-end consumer electronics, the perovskite-based LEDs, developed by researchers at the University of Cambridge, ca 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
