Robust, Strongly Luminescent, and Highly Dispersible Hybrid Materials

Hybrid structures incorporating ionic and coordinate bonds

Invention Summary:

Hybrid structures built on cluster based charge-neutral CumIm modules (e.g. Cu4I4 cubane tetramer) typically have higher luminescence efficiency compared to inorganic modules with higher dimensions, such as a 1D chain or 2D layer of (CuI). Structures with strong emission an enhanced stability can be achieved by incorporating highly emissive inorganic cores and strong binding ligands to make extended multidimensional networks. Limitations to these materials include low blue-light excitability and poor solution processability.

Researchers at Rutgers University have developed a novel class of molecular (0D) and chain-like (1D) phosphor compounds CumXm+n(L)n, with high chemical and thermal stability. More significantly, the hybrid materials exhibit strong blue-light excitability and excellent solution processability as a result of incorporating both ionic and coordinate bonds within the structure. They are promising candidates for use as rare-earth-element free phosphors in conjunction with the blue chips as in the current commercial WLEDs.
