Efficient multilayered high yellow polymer light emitting devices were successfully fabricated using a solution processed n doped small molecular electron transporting layer composed of 1,3,5 tris(N phenyl benzimidazol 2 yl) benzene (TPBi) and Cs 2 CO 3 . We found that the electroluminescence properties of the devices with Cs 2 CO 3 doped TPBi electron transport layers (ETL) are significantly improved. The maximum luminance eff iciency of the device with Cs 2 CO 3 doped TPBi ETL reached 6.7 cd/A, which is 20% higher as that of the undoped device. These results demonstrate that Cs 2 CO 3 can be used as an effective n dopant in solution processed devices..

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.
