氣體對平面電子發射光源元件影響之研究
The Influence of Gas on Flat Electron Emission Lamp Device
摘要
平面電子發射光源(Flat Electron Emission Lamp, FEEL)為原創之新型發光源，其工作原理是利用外加電場加速電子激發螢光粉之方式發光，因此不會有紫外光的產生。而電子主要有兩種來源：一為氣體游離產生自由電子；二為離子化氣體原子撞擊陰極材料後發射二次電子。經實驗發現，FEEL除了擁有雙面均勻發光之特色外，適當的調配不同條件的螢光粉，還可設計出透明、灰階或彩色圖案之平面光源與應用。 本論文將針對FEEL元件在不同製程與氣體條件下，設計一系列實驗瞭解它們對FEEL元件壽命的影響，包括不同氣體電漿前處理條件與不同工作氣體下之影響研究，進而提昇FEEL元件之效率。

Flat Electronic Emission Lamp (FEEL) is a new pattern of light source with the theory of luminescence utilizing electrons being accelerated by external electronic field to excite the phosphor powders without having UV light emitted. The above mentioned electrons can be generated from two different sources, one is the free electrons from gas ionization, and another source is the secondary electrons generated from the bombardment of ionized gases to the cathode material. It was found by our team that there are advantages of utilizing FEEL: generate uniform double-side lighting, and, with the proper formulation of phosphor slurry, can create transparency, gray-scale, or color image, as well as for further relevant applications. Purpose of this thesis is to identify the factors that can affect FEEL device’s lifetime and efficiency under different process and gas condition, which include the treatment of gas plasma condition, and the influence of different working gases. After the identification of influential factors, the lifetime and efficiency of FEEL devices can be upgraded accordingly.
