Abstract

Large single-crystals of the cetineite-type phases (Rb;Se), (Sr;Se) and (Ba;Se) have been synthesized by hydrothermal reactions and single-crystal X-ray analyses with atomic resolution together with the electrical and optical measurements confirm a trend in the optical gap related to the chemical composition.
