| 1 | Improved Quantum Efficiency of Organic Light Emitting Diodes with Gradiently Doped Double Emitting Zone显示文摘We investigate electroluminescent characteristics of gradiently doped organic light-emitting diodes, which were gradiently doped in both the hole and the electron-transporting layer to form a double emitting zone. The device structure was ITO/(15nm) CuPc/(60nm) NPB:rubrene/(30nm) Alq3:rubrene/(20nm) Alq3/(0.5nm) LiF/Al. We observed that charge carriers were well trapped by the dopant molecules and the main emitting zone was localized at the NPB:rubrene side close to the interface of NPB:rubrene/Alq3:rubrene. The quantum efficiency (cd/A) was enhanced to 5.89cd/A at 6V. We attributed this improvement to the charge carriers trapping and the emitting of the double emitting zone. | GAOWen-Bao JIANGWen-Long SUNJia-Xin PENGJing HOUJing-Ying LIUShi-Yong | 2003 | Chinese Physics Letters2003，20，6： | 5 |
| 2 | The occurrence of the genus Marrella(Trilobitoidea) in Asia显示文摘An important discovery in the Kaili Biota has been made recently, and many interesting components from Chengjiang Biota and Burgess Shale Biota have been discovered. Among them Marrella, only known from mid-Middle Cambrian Burgess Shale Biota of British Columbia, Canada, is one of the most important arthropods fossils. Because the Kaili Biota is older than the Burgess Shale Biota, the strange head shield of Marrella occurring in the Kaili Biota outside Laurentia ranges from mid-Middle Cambrian to early Middle Cambrian and is significant for the reconstruction of palaeogeography and evolutionary study of early metazoa. In the present paper Marrella sp. is reported for the first time in Asia. | ZHAOYuanlong YUANJinliang ZHUMaoyan YANGXinglian PENGJing | 2003 | Progress in Natural Science:Materials International2003，13，9： | 2 |
