В этой работе были определены оптимальные параметры получения наночастиц сульфида свинца (PbS). Наночастицы сульфида свинца были получены методом химического осаждения в водном растворе нитрата свинца (Pb (NO3 )2 ) 25 мл 0,18 М (1,524 г), гидроксида натрия (NaOH) 75 мл 0,38 М (1,172 г), тиомочевины (CH4 N2 S) 50 мл 0,11 М (0,399 г), при температуре реакции 100 °C, длительность реакции синтеза составляла 120 минут. Частицы осаждались на предварительно очищенной кремниевой (Si) подложке. После синтеза частицы были обработаны в плазме тлеющего разряда в атмосфере аргона при давлении порядка t1 =1 Па, в течение t1 =1 мин и I =1,5 мин., при напряжении I =1,5 кВ и силе тока I =1,5 мА. Морфология полученных структур была исследована с помощью сканирующего электронного микроскопа (СЭМ), элементный состав частиц определялся методом энергодисперсионного анализа (EDX). Обработка плазмой приводит к уменьшению среднего размера частиц от субмикронного до нанометрового диапазона.

In this work, the optimal parameters for the production of lead sulfide nanoparticles (PbS) were determined. Lead sulfide nanoparticles were obtained by chemical precipitation in an aqueous solution of lead nitrate (Pb(NO3 )2 ) 25 ml 0.18 M (1.524 g), sodium hydroxide (NaOH) 75 ml 0.38 M (1.172 g), thiourea (CH4 N2 S) 50 ml 0.11 M (0.399 g), at a reaction temperature of 100 °C, the duration of the synthesis reaction was 120 minutes. The particles were deposited on a pre-purified silicon (Si) substrate. After synthesis, the particles were processed in a glow discharge plasma in an argon atmosphere at a pressure of the order of Ð=1 Pa, for t1 =1min and U = 2 min, at a voltage ofU = 2 kV and a current strength of I =1,5 mA. The morphology of the obtained structures was studied using a scanning electron microscope (SEM), the elemental composition of the particles was determined by energy dispersion analysis (EDX). Plasma treatment reduces the average particle size from the submicron to the nanometer range.
