過渡元素與稀土元素摻雜矽酸鋅主體是良好的發光材料。利用UV光或陰極射線激發矽酸鋅摻雜錳螢光粉體放射出高效率的綠光，所以廣泛應用在CRT、電漿電視。矽酸鋅摻雜銪螢光粉體為良好的紅光材料，也被應用於一般TV電視和CRT。
本研究利用固態法合成矽酸鋅摻雜錳、銪離子，探討不同摻雜量對矽酸鋅螢光主體之發光特性與結構特性。在錳添加量為4mol%時有最佳之綠光發光強度，在銪添加量為5mol%時有最佳之紅光發光強度。本實驗也發現矽酸鋅摻雜錳離子在反應持溫時間12小時有最佳之發光特性。
最後探討利用不同錳離子起始原物料對矽酸鋅主體發光特性與結構特性之影響，發現氧化錳發光特性比碳酸錳強，但主要放射波段並無改變。

Transition and rare-earth ions doped zinc silicates are efficient lumi- nescent materials. Mn2+ doped Zn2SiO4 phosphors emit green light when excited by UV light or cathode ray. These materials have been widely in- vestigated in cathode ray tubes (CRTs) and plasma display panels due to their high luminescence efficiency. Similarly, Zn2SiO4：Eu3+ has strong emission in the red, and that make it applicable to TV and CRT screen.
In this thesis,We studied manganese and europium ion doped zinc silicates by solid state reaction in air atmosphere, and investigated the characterrization of luminescence and structure in zinc silicates with different dopant amount. There is an efficient green light when the man- ganese doped is 4mol%. Similarly, the efficient red light is happened when the europium doped is 5mol%. Zn2SiO4:Mn2+ is efficient lumine- scent materials when the lasting temperature is 12hr.
Last, we studied that the influence of luminescence in zinc silicates by different original material of manganese. The luminescence property of MnO in zinc silicates is better than MnCO3, but that is not effects the emission spectra.
