Abstract

The (Y,Gd)BO₃:Eu³⁺ phosphor was made by coprecipitation method. The precipitated powders were amorphous. The value of pH in the process of coprecipitation was critical for the luminescence of phosphors. The particle size and morphology were influenced by pH value. The lower calcination temperature and hydrothermal synthesis leads to the distortion of lattices. The distorted lattices changed the symmetry of Eu³⁺ site. The broken inversion symmetry in the distorted lattice caused the increased emission of⁵ D₀→⁷D₂ transition.
