Аннотация:

Предмет исследования. Бессвинцовые нанокристаллы перовскита, их основные характеристики, методы синтеза и оптические свойства. Цель исследования. Проведение анализ литературных источников по методам синтеза и оптическим свойствам бессвинцовых нанокристаллов перовскита (бПНК). Определение процесса формирования бессвинцовых нанокристаллов перовскита, основные методы синтеза. Установление зависимости размера и значения квантового выхода фотолюминесценции от параметров синтеза, таких как метод, температура, тип лиганда. Основные результаты. Был проведён анализ литературных данных по теме «Методы синтеза и оптические свойства бессвинцовых нанокристаллов перовскита». Определено, что формирование бессвинцовых нанокристаллов перовскита происходит по моделям Ла Мера и кластерной модели. Анализ литературных данных показал, что основными методами получения бессвинцовых нанокристаллов перовскита являются метод горячего впрыска и переосаждения в присутствии лигандов. Было показано, что увеличение температуры реакции приводит к увеличению среднего размера бессвинцовых нанокристаллов перовскита. Было установлено, что для бессвинцовых нанокристаллов перовскита, полученных методом переосаждения в присутствии лигандов, увеличение температуры реакции до 100 °С приводит к незначительному уменьшению значения квантового выхода, в то время как для бессвинцовых нанокристаллов перовскита, полученных методом горячего впрыска, значение квантового выхода фотолюминесценции практически не зависит от температуры. Было показано, что использование олеиновой кислоты в качестве лиганда приводит к формированию бессвинцовых нанокристаллов перовскита с малым разбросом по размерам, в то время как наибольшие значения квантового выхода фотолюминесценции наблюдались для бессвинцовых нанокристаллов перовскита, синтезированных в присутствии смеси лигандов. Практическая значимость. Анализ литературных источников показал, что наиболее перспективным методом синтеза бессвинцовых нанокристаллов перовскита является метод переосаждения в присутствии лигандов, так как он проще в реализации, более энергоэффективный и может быть масштабирован. Полученные таким методом бессвинцовые нанокристаллы перовскита могут применяться в качестве активного материала для устройств сенсорики, фотовольтаики и оптоэлектроники.
