| 摘 要： | 制成了用三价Ｔｂ配合物作为发射层的有机电致发光二极管，并获得纯Ｔｂ３＋的发光光谱。二层结构为玻璃衬底／Ｉｎ－ＳｎＯ（ＩＴＯ）／ｐｏｌｙ（Ｎ－ｖｉｎｙｌｃａｒｂａｚｏｌｅ）（ＰＶＫ）／Ｔｂ配合物／Ａｌ，在正向直流偏压下发出明亮的绿光。器件的电致发光（ＥＬ）光谱与Ｔｂ配合物薄膜的光致发光（ＰＬ）光谱完全一致，含有一个尖锐的发射带，系典型的Ｔｂ配合物的发光谱。在驱动电压为５Ｖ下，发光清晰可见，当驱动电压达到１５．４Ｖ时，获得２１０ｃｄ／ｍ２的发光，据知这是用Ｔｂ配合物做发射层的电致发光元件的最亮的发光。同时，通过对器件光谱及电学特性的测量、比较和分析，探讨了有关稀土电致发光机理等问题

| Abstract: | Organic Electroluminescent (OEL) devices using trivalent terbium (Tb)complex as emitter were fabricated. The cell structure was glass substrate/In SnO(ITO).poly(N vinylcarbazole)(PVK)/Tb complex/Al, the hole transport layer and the emitter were fabricated by spin coating on ITO and vacuum deposition, respectively. The EL spectrum consists of sharp emission lines from Tb 3+ ions. Luminance of 210 cd/m 2 was achieved at drive voltage of 15.4 V. This is the highest luminance so far we know, obtained from the OEL cells with Tb complex as emitter. The theory of rare earth's luminance is discussed through measuring and comparing the cell's spectra and electric property. |
