Development of gas-solid phase hybrid synthesis method of single crystal Ba2SiO4:Eu2+

We succeeded in the single crystal growth of Ba2SiO4:Eu2+ by novel synthesis method which was gas (SiO) and solid (Ba - Sc - Al - Eu - 0) 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 mu m sizes and emitted green light around 500 nm under 300 - 450 nm excitation.
