ABSTRACTA series of uranium-containing gadolinium zirconate samples have been fabricated at 1723 K in air. X-ray diffraction and Raman spectroscopy have confirmed pyrochlore or defect fluorite structures, while diffuse reflectance, X-ray absorption near edge structure and X-ray photoelectron spectroscopies indicate a predominantly U6+ oxidation state, even when Ca2+ was added to charge balance for U4+. The results demonstrate the potential of gadolinium zirconates as host materials for actinides.

By adjusting the triazole/carbazole ratio, the charge injection and charge balance of novel bipolar host materials are regularly tuned, and 1 : 2 is proved to be the optimal ratio leading to highest efficiencies and slowest efficiency roll-off in blue and green phosphorescence organic light-emitting diodes.
