Enhanced luminescence of CuCl microcrystals in a organic-inorganic hybrid matrix

Gamma-CuCl microcrystals were found to segregate in self-assembled [CnH(2n+1)NH3]2CuCl4 hybrid organic-inorganic films deposited by single source thermal ablation. The microcrystals dispersed in the hybrid have sizes of 35 nm, as estimated from X-ray diffraction patterns. The UV photoluminescence efficiency of the embedded microcrystals is more than 100 times higher than that of CuCl films having similar crystallite sizes.
