Пленки осаждали из коллоидных растворов КТ в нитробензоле, содержащих наночастицы с диаметром от 3,4 до 6,3 нм. Электрохимическое поведение и оптический отклик изучали методами циклической вольтамперометрии (ЦВА) и in situ спектроскопии поглощения в пленках, нанесенных на прозрачные проводящие стекла. В инертной атмосфере при заряжении КТ наблюдается обратимое изменение окраски (электрохромизм) за счет подавления экситонного поглощения, при котором изменение оптической плотности достигает 0,3. Путем численного моделирования ЦВА и сопоставления с экспериментальными данными было показано, что механизм электрохимического заряжения включает стадии переноса электрона с подложки на КТ, межчастичный перенос, а также захват электронов акцепторами в растворе. Введение активного акцептора электронов (O2) в раствор приводит к подавлению электрохромизма. Эффект влияния окислителя обратим и после вытеснения кислорода из раствора аргоном позволяет повторно и многократно наблюдать электрохромизм в КТ селенида кадмия.</p></abstract><trans-abstract xml:lang="en"><p>Electrochemical charge/discharge mechanisms in the electrophoretically deposited CdSe quantum dot (QD)film electrodes in NBu4PF6 acetonitrile solution have been investigated. The films were deposited from CdSe colloidal solution in nitrobenzene at variable QD size (diameter) from 3.4 to 6.3 nm onto transparent conducting glass substrates. Electrochemical behavior and optical response were characterized by cyclic voltammetry (CV) and in situ absorption spectroscopy. Electrochemical charging under an inert gas atmosphere results in a reversible color change (electrochromism), due to the bleach of exciton absorption with 0.3 optical density changes. The mechanism of electrochemical charging comprises electron transfer from conducting substrate to QD, interparticle transfer and also electron capturing by acceptors in solution. The introduction of a strong electron acceptor (O2) into the solution results in a suppression of electrochromism. The influence of oxygen is rather reversible which is observed from recovered electrochromic behavior after electrolyte resaturation with argon.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>квантовые точки</kwd><kwd>селенид кадмия</kwd><kwd>циклическая вольтамперометрия</kwd><kwd>электрохромизм</kwd><kwd>экситонное поглощение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>quantum dots</kwd><kwd>cadmium selenide</kwd><kwd>cyclic voltammetry</kwd><kwd>electrochromic materials</kwd><kwd>exciton absorption</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Белорусского республиканского фонда фундаментальных исследований (проект № Х20-037).</funding-statement><funding-statement xml:lang="en">This work has been performed with a financial support of the Belarusian Republican Foundation for Fundamental Research (Project № Х20-037).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rogach, A.
