Sol-gel synthesis and characterization of mixed-metal garnet Y_3ScAl_3GaO_(12) (YSAGG)

摘要

Aluminates having different crystal structures are promising materials for optical applications [1,2]. These oxides are attractive host materials for the development of advanced phosphors with their general chemical stability. Phosphors are key materials in fluorescent lighting, displays, scintillation, etc. Although the search for advanced phosphors started about a century ago, the new photonic technologies, including mercury-free fluorescent lamps, various flat panel displays, computed tomography, etc., require new phosphors with advanced properties [3-5]. However, the discovery of advanced oxide phosphors with multiple superior qualities for display applications remains difficult [6], since the specific luminescence properties are highly sensitive to the changes in dopant composition, host stoichiometry, and processing conditions.
