| Popis: | The formation of multifunctional ordered arrays of detonation diamond particles is studied during self-assembling in spin coating of films of evaporating microdroplets. It is shown that the most homogeneous layer of diamond particles on a crystalline silicon substrate forms at a rate of substrate rotation of 8000 min–1, whereas a relation between the distribution of particles and the radius is clearly detected at rates of about 2000 min–1. As the rate of substrate rotation increases from 2500 to 8000 min–1, the density of the coating of a silicon substrate with diamond nanoparticles decreases approximately threefold. A model is proposed to estimate the increase in the number of individual diamond “points” with the substrate rotation frequency. |
