A New Photorefractive Material KNSBN; Co,
Abstract
Potassium sodium strontium barium niobate (KNSBN) has been developed in our country for the first time. It is a new ferroelectric with A-sites thoroughly occupied by K+, Na+, Sr2+ and Ba2+ ions. Comparing to BaTiO3, KNSBN crystals have no phase transition at room temperature, but have large hardness coefficient and 180 deg ferroelectric domains that are easy to be polarized. KNSBN will be one of the most prospective photorefractive materials that can be used in holographic storage, image amplification and optical phase conjugation. The purpose of this paper is to describe the crystal growth and photorefractive properties of KNSBN:Co.
