Development of Gas-Solid Phase Hybrid Synthesis Method of Single Crystal Ba₂SiO₄:Eu²⁺

Abstract:

We succeeded in the single crystal growth of Ba₂SiO₄:Eu²⁺ by novel synthesis method which was gas (SiO) and solid (Ba - Sc - Al - Eu - O) phase hybridized. The Ba₂SiO₄:Eu²⁺ single crystal was synthesized by interfacial crystal growth after the reaction of the SiO gas with the surface of Ba - Sc - Al - Eu - O substrate in the reductive atmosphere. The single crystals were plate-like crystals with about 500 μm sizes and emitted green light around 500 nm under 300 - 450 nm excitation.
