網印奈米碳管製作螺旋圖案場發射平面光源
PRINTING CARBON NANOTUBES TO FABRICATE THE SPIRAL PATTERN FIELD EMISSION FLAT LIGHT SOURCE
摘要
本論文的研究著重於利用奈米碳管優異的場發射特性製作一個兩吋以內的螺旋圖案奈米碳管場發射平面光源以及在照明方面的應用。我們使用數種陰極基板與陰極電極去分析不同參數下的場發射特性，而且運用厚膜網印技術網印不同圖形奈米碳管到陰極基板上也對場發射特性有很大影響，另外我們網印數種不同螢光粉到陽極基板上來增進螢光粉在場發射量測的亮度及均勻性。我們製作二極式、反射式、線條二極式與三極式場發射元件，並比較彼此不同的特性，不論是場發射特性、亮度、均勻性，在本論文內有詳細的描述。在陽極部份，我們可以運用不同的結構、製程與材料，製作出擁有高亮度、均勻性佳、薄型平面的螺旋圖案奈米碳管場發射平面光源，且螺旋圖案奈米碳管場發射平面光源擁有優異的場發射特性，適合多種照明上的應用。

The study of this thesis focuses on the fabrication and investigation of the excellent carbon nanotubes field emission flat light source with a spiral cathode pattern that the diameter is less than 2-inch for lighting application. Several substrates as the cathode and several materials of the electrode have been used in the study for the analysis of characteristics of the parameters. The field emission properties strongly depend on the pattern of the cathode by the method of thick-film printing. We have also used several phosphors as the anode materials to improve the light brightness and uniformity. Some panel structures, such as diode, line diode reflective type diode, and triode structure, have been made and investigated for the comparison. The results of field emission properties, brightness, and uniformity are also shown in the this thesis, and the spiral cathode structure field emission flat light source has very excellent properties, such as high brightness, uniformity, and flexibility in the structure for different lighting application.
