陰極材料對平面電子發射光源元件之影響

平面電子發射光源（Flat Electron Emission Lamp, FEEL ）為一新型之發光光源，其發光機制結合了螢光發光FL（Fluorescent Lamp）及陰極發光CL（Cathodo-luminescence）而成之無汞發光源。平面電子發射光源其結構簡單，僅由兩片玻璃及一間隔物結合而成；元件製作過程中，不需添加汞且不會排放有毒物質，為一環保製程；發光特性方面，此為平面式光源，具有均勻發光之特性。由FEEL元件結構可以發現，影響FEEL元件效益之因素主要可分為陽極螢光粉、陰極材料及氣體種類三部分。本論文研究主要探討陰極材料對FEEL元件之影響，陰極材料包含不同製程濺鍍之ITO導電薄膜及不同材料（FTO、Al及SnO2），藉由不同製程之ITO及不同陰極材料之特性，歸納影響電流下降之主要因素，而後在陰極導電膜上沉積保護層（Al2O3及MgO），藉此更有效提升FEEL之使用壽命。

Flat Electron Emission Lamp (FEEL) is a new type of light source that combines the lamp mechanisms of fluorescent lamp(FL) and cathodoluminescence(CL). FEEL was the simplest structure which was constituted by two pieces of glass and a spacer. There is no mercury added during the process, so it is environmental-friendly. Besides, FEEL is a flat light source and it could radiate uniform light. The main effect factors of FEEL devices are phosphor, electrode material and gas. In this research, we tried to find the influence of cathode material on FEEL devices. The cathode materials included ITO thin film with different deposited processes, FTO, Al and SnO2. Moreover, protective layer (Al2O3 and MgO) was also deposited on conductive thin film to extend the lifetime of FEEL.
