Strongly emissive white-light-emitting silver iodide based inorganic–organic hybrid structures with comparable quantum efficiency to commercial phosphors

Abstract

A series of one-dimensional silver iodide based inorganic–organic hybrid structures with tunable white light emissions have been synthesized by Cu substitution. The white-light-emitting hybrid 1D-Ag_2−xCu_xI₂L₂ (x < 2, L = ligand) compounds exhibit extremely strong luminescence with internal quantum yield (IQY) as high as 95%, significantly higher than most of the previously reported direct white-light-emitting hybrid structures and comparable to the IQYs of commercial phosphors.
