Study On The Impact On Optical Properties Of Yag:Ce³⁺ Via Different Crystals Al₂O₃and The Preparation Process

YAG:Ce³⁺is the important business in the field of solid state lighting lightconversion material, its unique optical properties of enduring in the field of solid statelighting, which has become a focus for researchers. The reasonable control of theirsize, morphology control, thus achieving its luminous efficiency and the optimizationof its synthesis process, has important theoretical and application value. Select the rawmaterials involved in the YAG:Ce³⁺phosphor preparation process, the exploration ofthe complete innovation process and the preparation conditions on the impact of theYAG:Ce³⁺phosphor performance. Innovation for which content has the followingmain points:On the choice of raw materials, the preparation conditions and process systemexperiments, conducted a comprehensive analysis of the impact of various factors,summarized and summarize the conclusion of industrial production has producedsome guiding significance, and further from the theoretical analysis of differentcrystalline alumina of YAG:Ce³⁺fluorescence properties and microstructure of theexperimental basis.2, we selected several different crystalline form of alumina as raw material,under the conditions of industrial production, barium fluoride as a cosolvent, thesynthesis of highly efficient YAG:Ce³⁺phosphor （α1-YAG, α2-YAG, γ-YAG andδ-YAG）. The best performance of the synthesized phosphor luminous intensity ofabout7%higher than the existing standard commercial phosphor. 3, the lattice parameters of the alumina raw material and found that close contactwith the YAG unit cell parameters, and infer the impact factor of the crystal type ofsample performance, given the reaction mechanism.In summary, the purpose of thisstudy, is that by optimizing the existing process preparation process and select themost suitable raw materials as YAG:Ce³⁺phosphor production, which enables theoptical performance of the industrial production of YAG:Ce³⁺phosphor to the best,and that the result of some guiding significance of existing industrial production.
