Unexpected Coulomb Interactions in Nonpolar Solvent for Highly Efficient Nanoxerography of Perovskite Quantum Dots

“…The commonly used zeta potential measurement technique often fails in the case of nonpolar solutions. Fortunately, in the last two decades, new methods have been developed, allowing a quantitative analysis of the charge state as well as the NP–substrate interactions. , For instance, using electrostatic force microscopy (EFM), one can measure the net charges carried by a single nanoparticle, as well as the potential distribution on a charged nanopattern; , using the spatial occurrence possibility of NPs, one can calculate their trapping potential distribution . Inspired by these developments, in this work, we study the charge state of NPs and their interactions with nonuniform electric fields using different tools, with the goal of developing a highly efficient nanoxerography technique for high-quantity functional NPs synthesized in oils.…”
