摘要: | 本論文探討如何將陰極射線管用之螢光粉應用於低壓場發射顯示器,其中將會遭遇兩個主要的問題,一個是螢光粉表面的非發光層以及螢光粉本身的高電阻率的問題。其中螢光粉的高電阻率的問題,必須去降低高電阻率以防止螢光粉在低電壓操作下,其表面會有charging-up現象的產生,因此在此將利用InCl3來改善其在低壓的發光特性。而另一個問題螢光粉表面的非發光層的存在,則是將利用酸性濃液蝕刻螢光粉,以去除此不發光層的存在,而來提昇螢光粉的發光亮度及效率。 An investigation of the CRT phosphors applied to FED phosphors at low voltage. Two main obstacles are non-emissive layer of phosphor surface and high resistivity of phosphor. The high resistivity of CRT phosphors is necessary to lower in order to reduce charging-up on the phosphor surface at low voltage. In this study, InCl3 is utilized to improve the low voltage cathodoluminescent properties. The non-emissive layer of phosphor is etched with a aqueous solution of acid. The etching results in an increase of cathodoluminescenct efficiency without any detected change in surface composition as detected by Auger electron spectroscopy. The low-voltage cathodoluminescent characteristics are particularly enhanced. |
