Влияние влажности бензойной кислоты на процесс протонного обмена в кристаллах ниобата лития
Аннотация
Цель данной работы – изучение влияния примесей воды в бензойной кислоте, используемой в качестве источника протонов при проведении протонного обмена на кристаллах ниобата лития, на процесс формирования протонообменных волноводов, их структуру и фазовый состав.
Для проведения исследований использовались методы призменного ввода, рентгеноструктурного анализа, спектроскопии ИК-поглощения, оптической микроскопии в поляризованном свете. Установлено, что увеличение содержания влаги в бензойной кислоте оказывает влияние на оптические характеристики волноводов, несколько увеличивает напряжения (деформации) протонообменных слоев. Последующий отжиг в значительной мере выравнивает характеристики волноводов.
При проведении протонного обмена следует учитывать содержание влаги в бензойной кислоте для получения воспроизводимых и стабильных характеристик интегрально-оптических устройств с протонообменными волноводами
