- 論文の詳細を見る
We investigated the effects of heat treatment on the data storage performance of strontium barium niobate doped with cerium and europium. The photorefractive writing sensitivity was increased by elevating the annealing temperature. When the annealing was undertaken at a high temperature, for example 900℃, the sensitivity reached a value about ten times that obtained at an annealing temperature below 600℃. This increase was caused by a photoconductivity increase which was probably due to an increase in the oxygen vacancy concentration. The page multiplexing performance of the crystal is also discussed in relation to the photorefractive trap density.
