Abstract: Li₂SiO₃:Eu³⁺ phosphor precursor was prepared via a simple ball-grinding solid state reaction at room temperature using LiOH·H₂O,Si(OC₂H₅)₄ and Eu(NO₃)₃·6H₂O as raw materials,then after calcination at high temperature,a series of Li₂SiO₃:x% Eu³⁺ red phosphors were obtained.The influences of calcining temperature,dwelling time and Eu³⁺ contents on the structure and luminescent properties of as-prepared phosphors were investigated.The results indicated that the phase composition of Li₂SiO₃:x% Eu³⁺ did not change with the increase of Eu³⁺ content when x was in the range of 1.5 to 15,and the concentration quenching phenomenon did not appear until the value of x reached 12.When the calcining temperature was 1 173 K and the dwelling time was 2 h,the luminous intensity of the fluorescent system reached the maximum value.The Li₂SiO₃:Eu³⁺ phosphors showed an intense red emission,corresponding to the ⁵D₀→⁷F₂ (615 nm) transition of Eu³⁺under 467 nm excitation.
