Giant Photoluminescence Enhancement in CsPbCl3 Perovskite

The presence of localized trap states on the surface of CsPbCl3 perovskite nanocrystals NCs is one of the greatest challenges precluding the development of optoelectronic applications of these NCs. Passivation of these defect sites provides a promising pathway to remediating their electronic and optical properties, such as the photoluminescence quantum yield PLQY. Herein, we demonstrate a

Size Reduction Visual Encyclopedia of Chemical Engineering

A colloid mill rotor is an intermeshing rotor used for the size reduction of materials by multiple impacts with the maze of pins. High speed rotation applies fluid shear stress, inducing the breakdown of agglomerates. The speed of the rotation can also be reduced during mixing to induce a smoother impact and avoid material degradation while still producing enough turbulence to create a
