Features of the deposition of photonic crystal films of polystyrene and silica

The paper presents the results of research in the field of deposition technology for self-organizing colloidal films. Such structures can be used in the manufacture of controlled photonic crystal devices. Therefore, it is important to determine methods and modes of obtaining high-quality ordered periodic opal structures. We compare the methods of vertical deposition and electrophoresis and discuss the features of their application in the deposition of films formed from colloidal particles of polystyrene and silica. We have found that vertical film deposition when the substrate is pulled out of the colloidal suspension is the most technologically convenient and suitable for both materials. The electrophoresis method is more difficult to implement, but it allows you to control the deposition process in dynamics. n this article, we present the identified rational modes of obtaining photonic crystal films by both methods.
