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.
