Updated: New Inorganic Emitters for Phosphorescent LEDs on Frontispiece of Advanced Materials

Richard Lunt’s group in the MSU Dept. of Chemical Engineering has developed a new class of LEDs based on hexanuclear metal halide clusters.  These clusters exhibit a broad emission spectrum which we attribute to an unusually strong Jahn-Teller distortion in the excited state which arises from the existence of both global (whole cluster) and local (immediate neighborhood of each metal atom) symmetry in the clusters.  Check it out.

Update:  This work is on the frontispiece of Advanced Materials!
