Paper Abstract

Formation of single-crystal opal films from a suspension of monodisperse spherical silica particles in a dynamic meniscus area is treated as nanocrystallization involving interparticle interaction forces. Preparation of high-quality photonic-crystal films with a reflection coefficient in the photonic band gap up to 95% is based on the concept of equilibrium crystallization. In practice, this process occurs through the correction of oppositely directed interparticle interaction forces down to a quasi-equilibrium state. Two- and three-layer heterostructures have been produced from single-crystal films with various sizes of silica spheres. Well-resolved allowed ranges within photonic band gaps have been detected for three-layer heterostructures, suggesting interesting applications of photonic crystals.
