Gel permeation chromatography process for highly oriented Cs(3)Cu(2)I(5) nanocrystal film

The emergence of green materials has attracted considerable attention in the field of optoelectronics. Copper-based lead-free metal halide (with a near-unity quantum yield) obtained from Cs(3)Cu(2)I(5) nanocrystals (NCs) can exhibit blue emission with a wavelength of 440 nm and provide outstanding s...

description The emergence of green materials has attracted considerable attention in the field of optoelectronics. Copper-based lead-free metal halide (with a near-unity quantum yield) obtained from Cs(3)Cu(2)I(5) nanocrystals (NCs) can exhibit blue emission with a wavelength of 440 nm and provide outstanding stability for various applications. However, in practical applications, colloidal dispersion purity and film quality are inadequate toward a high-performance device. In this study, antisolvent-free gel permeation chromatography is used to purify Cs(3)Cu(2)I(5) NCs. The purified Cs(3)Cu(2)I(5) NCs exhibit a high photoluminescent quantum yield and provide a highly oriented single-crystal film. Density functional theory calculation results indicate that the iodide-rich surface in the NCs makes them highly stable. In addition, it has been demonstrated for the first time that the mixture of polymethyl methacrylate (PMMA) and Cs(3)Cu(2)I(5) NCs has waterproofing capabilities. The composite film consisting of Cs(3)Cu(2)I(5) NCs and PMMA can survive in water for several days. This result opens up more possibilities for the application of these green material.
