A New Copper(I) Iodide Based Organic-Inorganic Hybrid Structure with Red Emission

A new organic-inorganic hybrid structure based on copper (I) iodide staircase chain 1D-Cu2I2(5-chloropyrimidine)2(1) has been synthesized by a slow-diffusion method. It emits red emission peaking at 620 nm. The internal quantum yield (IQY) measured for this compound is 6.5% under 360 nm excitation. This compound exhibits potential as a non-rare-earth light-emitting phosphor alternative.Keywords:copper iodide;organic-inorganic hybrid;phosphor
