Research on Particle Size and Luminescence Properties of GdBaB₉O₁₆: Eu³⁺Phosphor Prepared by Sol-Gel Method

Abstract:

Gd_0.6BaB₉O₁₆: Eu³⁺_0.4 red phosphors were prepared by sol-gel technique. The different polyethylene glycols (PEGs) were added to control the particle size ofGd_0.6BaB₉O₁₆: Eu³⁺_0.4. The particle distribution and the relationship between the particle size and the luminescence properties of the phosphors were investigated. PEGs have no influence on the structure ofGd_0.6BaB₉O₁₆: Eu³⁺_0.4, but the particle size is changed with different molecular weight of PEGs. And the relative intensity of excitation peak and emission peak ofGd_0.6BaB₉O₁₆: Eu³⁺_0.4phosphor are reduced by adding PEG, due to the particle size effects.
