Blue-excitable-yellow-emitting copper iodide inorganic-organic hybrid structure with quinoxaline derivative

Abstract Here, a copper iodide inorganic-organic hybrid structure 1D-CuI(4-Cl-qnx) (1, 4-Cl-qnx = 4-chloro-quinoxaline) has been reported. It is a blue-excitable-yellow-emitting phosphor with internal quantum yield (IQY) of 31.2 % under 450 nm excitation, showing promise as a rare-earth free lighting phosphor for white-light LEDs.
