Highly Soluble and Eco-friendly Luminescent Hybrid Material for Lighting Phosphors

                                                  CuX-based AIO-type hybrid luminescent materials incorporating ionic and coordinate bonds


Invention Summary:

Copper Halide (CuX) based inorganic-organic hybrid luminescent materials (HLMs) are low-cost, non-toxic, highly stable, and offer strong luminescence with internal quantum yield of up to 98% @ 365 nm excitation. Yet, their major limitation is the poor solution processability.

Rutgers researchers have developed a novel class of copper iodide-based HLMs, named as all-in-one (AIO) structures, CumXm+n(L)n, which are highly stable and systematically tunable. More significantly, they possess excellent solution processability as a result of incorporating both ionic and coordinate bonds within the structure. They are promising, to be used as rare-earth element (REEs) free phosphors in conjunction with the blue chips as in the current commercial white light-emitting diodes (WLEDs). In addition, they show substantial potential for use as active emissive layers in LED devices.

 

Market applications:

  • Clean and/or renewable energy devices:
  • Solid-state lighting, LEDs
  • X-ray Detectors
  • Photovoltaics

Advantages:

  • Inexpensive
  • Low toxicity
  • High solution processability
  • Strong blue-light excitability
  • High luminescence quantum efficiency
