2015年7月11日 · No extra peak of Tb is seen in doped GaN nanocrystals and the same clear from wide scan. However, the XPS signal intensity of Tb4d ions decreases, while the intensity of the Ga–O bond increases. This suggests a decrease in Tb4d ions due to dissociation of O from Tb and formation of Ga–O bonds.
