Investigation of electro-optical properties of gradient potassium niobate

Abstract

The gradient perovskite material of potassium niobate is investigated in this work. As a result of the research, a gradient change in the properties was found: transformations of the IR absorption spectrum, the magnitude of the half-wave voltage depending on the composition of the grown potassium niobate crystal. The value of the half-wave voltage for plates cut from crystalline potassium niobate varied from 1500 to 1700 V with a change in the composition of potassium niobate in the range KxNb2-xO5-2x at x=0.9..1.
