This article describes the results of optimization of the colloidal photonic crystal opal films deposition by means of atomic force microscopy investigation. The main factors affecting the quality of the colloidal opal films are studied. Bragg diffraction occurs in the periodic distribution of colloidal microspherical particles, and ordered structure is critical for formation of the photonic band gap. It is found that polystyrene opal structures obtained in optimal conditions have a good periodicity, uniformity, and high packing density.
