We report a white stacked organic light-emitting device (SOLED) with high efficiency and low drive voltage by using Bphen:Li/WO3 as the interconnecting layer. The SOLED have been fabricated by connecting two low-voltage driving white units with conductive transport layers. The stacked two-unit device produced two higher luminance efficiency than that expected of a single-unit device. A maximum efficiency of 17cd/A was achieved by the stacked device comprised of two white-fluorescent OLEDs. It is also found that the power efficiency of stacked white organic light-emitting device is enhanced by 53% as compared to the control device..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
