Novel templates directed synthesis of YVO4: Eu3+ (red) and Y2O3–SiO2: Tb3+(green) phosphors

Red/green emissive phosphors YVO₄: Eu³⁺ and Y₂O₃–SiO₂: Tb³⁺ have been synthesized via novel templates direction methods. Photoluminescence studies exhibit the emission intensities as significantly enhanced through pre-encapsulation treatments of designed pyridine amide compounds (YVO₄: Eu³⁺) and 3,4,5-tris(tetradecoxy) benzoic acid (Y₂O₃–SiO₂: Tb³⁺). The as-prepared vanadate particles turn out to be much less agglomerated based on the dispersion by the organic templates. The obtained composite materials, which demonstrate extraordinary fluorescence properties, could be promising candidates for future optoelectronic devices.
