Данная работа посвящена исследованию эффективности применения эффекта допирования никелем тонких пленок на основе CdSe с возможностью вариации структурных и оптических свойств, обусловленной изменением фазового состава пленок. В качестве метода получения пленок был выбран метод электрохимического восстановления ионов металлов из водных растворов электролитов. Варьирование разности прикладываемых потенциалов было использовано для получения пленок с различными характеристиками. Для характеризации свойств и динамики их изменений были выбраны методы атомно-силовой микроскопии, энергодисперсионного анализа и рентгеновской дифракции. Прочностные механические свойства пленок были исследованы с применением метода индентирования. В ходе проведенных экспериментов получены зависимости изменения структурных, оптических, прочностных характеристик синтезированных пленок в зависимости от условий получения. Фотокаталитические испытания на определение скорости и эффективности разложения органического красителя Родамина В показали, что пленки в составе которых преобладает фаза NiSe обладают наибольшей перспективностью применения в качестве фотокатализаторов.
