Robust, Eco-friendly, Strongly Luminescent, and Highly Soluble Hybrid Materials

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

Invention Summary:

Copper halide (CuX) based inorganic-organic hybrid luminescent materials (HLMs) have distinct advantages including low-cost, non-toxicity, high stability, strong luminescence (IQY: ~98% @ 365 nm excitation and ~76% @ 450 nm excitation) and systematic tunability. They are excellent candidates for use as lighting phosphors that are totally free of rare-earth elements (REEs). However, the major limitation is the poor solution processability.

Researchers at Rutgers University have recently developed a novel class of copper iodide based HLMs, named as all-in-one (AIO) structures, CumXm+n(L)n, with all the advantages mentioned above. More significantly, they possess excellent solution processability as a result of incorporating both ionic and coordinate bonds within the structure. They are promising for use as REE-free phosphors in conjunction with the blue chips as in in the current commercial white light-emitting diodes (WLEDs). In addition, they show substantial potential for use as active emissive layers (EMLs) in LED devices.
