碩士 === 國立成功大學 === 化學工程學系碩博士班 === 92 === In this thesis, the solution combustion is used to prepared Zn2SiO4:Mn phosphor.
In the solution combustion process, because of the different gelation process of TEOS-gel or sol,the reactant can be divided into two different states. The different state induces different reaction process.How reactant state influence combustion product will be discussed, including of firing temperature, morphology, crystallinity and luminescent intensity. Besides, the effect of the calcining temperature and the concentration of activator are also discussed in this thesis. According to the experimental results, process parameters can be well understood. Comparing high luminescent phosphor with traditional solid state synthesis method will show it’s unique difference and homogeneity of the solution combustion.
In the solution combustion, the highest luminescent intensity can be achieved after calcining at 1200℃ with 3mol% Mn doped. At 1000℃,pure willemite crystal peaks appear in XRD analysis. In solid state method,the highest luminescent intensity can be achieved after calcining at 1200℃ with 4mol% Mn doped. But for solid state method pure willemite crystal peaks only appear in XRD analysis at 1200℃.
