The Studying of Components Ratio Influence in Mixed Monolayers of Quantum Dots and Arac hidic Acid on the Films Morphology Based on Them

The formation process of quantum dots stabilized by the trioctylphosphine oxide and arachidic acid molecules mixed monolayers was studied. An equation that determines a dependence of numbers of organic matrix molecules that separates quantum dots on e from each other in the close-packing Langmuir monolayer from quantum dots size was proposed. An existence of minimal numbers of organic matrix molecules for changing and tuning a distance between quantu m dots in the Langmuir monolayer was shown. The solutions with ratio between numbers of quantum dots and matrix molecule numbers of 1:5, 1:13, 1:26, 1:52 and 1:130 were studied. The mixed monolayers of indicated components ratio were studied by the compression isotherms method, transferred on solid glass substrates and studied via atomic force microscopy. An influence of components ratio in mixes Langmuir monolayers of quantum
