Formation of 2D colloidal crystals by the Langmuir–Blodgett technique monitored in situ by Brewster angle microscopy

We report a method that combines Brewster angle microscopy and Langmuir–Blodgett films technique to obtain highly ordered 2D colloidal crystals of nanospheres. The deposition of Langmuir–Blodgett films of silica spheres monitored by Brewster angle microscopy allows to determine with accuracy the best physical conditions to transfer highly ordered monolayers of nanoparticles.

A novel, easy and practical method that combines Brewster angle microscopy and Langmuir–Blodgett films to obtain highly ordered colloidal crystals templates of nanospheres is reported.Figure optionsDownload as PowerPoint slide
