摘要
奈米碳管已被證實很適合作為高亮度發光元件的場發射電子的發射子，其發光的機制和陰極射線管類似，都是利用電子去轟擊螢光粉激發可見光，本論文主要分成場發射光電量測與發光效率分析兩個部份。 在整個的實驗過程中，是利用三極結構來進行電子場發射實驗。主要是對陽極及閘極電壓做調整，並對該發光元件的陽極電流、發光亮度進行量測，將所測得的數據，利用工程分析軟體，繪製出陽極電流、發光亮度及發光效率等高曲線圖。個別分析上述等圖，可明確地辨識出實驗的變動參數組中，每個輸入的變動參數對量測值的影響程度。另外，如果對等高曲線圖群進行交叉分析，可以對照出量測值彼此相互的關係。 利用此方法，可以分析得到一些實驗結果，例如：陽極電流在陽極電壓 400 V 時，就已經逐漸進入電流飽和區；陽極電壓對發光亮度的影響是線性上升的關係等等。在先期場發射發光元件的開發進程中，這些被分析出的實驗結果可以協助研究人員，在眾多的亮度與發光效率之間的參數組合裡，選擇一個較為優化的條件作為參考範圍基準。

Carbon nanotubes has been demonstrate as suitable for highly bright of the electronic field emitter. And field emission technology is similar in operation to CRTs in that phosphor is excited by a stream of electrons. This paper is mainly consists field emission measurement and analysis of measure data. In during this experiment was use structure of triode electronic field emission. And adjust anode and gate voltage. Then measure anode current and brightness values. Using engineering analysis of graphics software, can made anode current and brightness and luminous efficiency contour plots. Analysis of above plots by individual, can clearly and identify both input parameters of variable, each other degree of the affect. Also, these plots to interactive analysis and compare measure values of each plot. Researchers can get each plot of relationship between. Use these methods to performing data process, then get analysis of some results. Such as: Almost anode current entering the current saturated region in anode voltage is 400V; Anode voltage on the brightness of the affect of increase is linear relation and so on. In the early procedural of develop of the field emission lighting device. Analyzed of these results can provide for researchers, as in many brightness and luminous efficiency between the parameters. Choice some optimum conditions for develop of basic reference of parameters range.
